Background: Guided by the green transformation of economic development, incorporating carbon peaking and carbon neutrality into ecological progress, and accelerating the formation of an industrial and energy structure that saves resources and protects the environment are the intrinsic requirements for China's high-quality economic development. The paper uses the DEA model and Malmquist productivity index to measure the economic development performance of 30 provincial units in mainland China, and summarizes the spatial-temporal evolution characteristics. Then, the Tobit model is used to analyze the influencing factors. Results: Our results show that: (1) The static performance of economic development generally showed an upward trend from 2008 to 2020, except for Beijing, Jilin, Heilongjiang, Guangdong, Hainan, Ningxia and Xinjiang, most of provinces had different degrees of input redundancy and output insufficiency. (2) The spatial distribution pattern of the static performance under carbon emissions constraint is dominated by the higher and high-level areas. As time goes by, the number of provincial units in different level areas tends to be stable, and the spatial distribution shows staggered layout characteristics. (3) The dynamic performance of economic development shows a downward trend from 2008 to 2016, and an upward trend from 2016 to 2020. The dynamic performance in most of provincial units has realized the transformation from the constraint of technological progress to the constraint of scale efficiency. (4) The urbanization level, economic development level, energy efficiency and the vegetation coverage are the main factors affecting economic development performance, while other factors such as industrialization level, environmental regulation, motorization level, openness and government intervention have no significant effect. Conclusions: This study suggests that China should adopt industrial structure transformation and upgrading, strengthen environmental regulation, promote new energy vehicles and introduce high-tech industries to improve economic development performance in the future.

Spiroaxillarone A, a novel and unique spirocyclic dinaphthalene natural product with significant antimalarial activity, was regioselectively synthesized from tetrahydrocurcumin in five steps with an overall 10% yield. Key features of the synthesis involved an oxidized free radical cycloaddition to build the spiro ring central skeleton and an oxidized dehydrogenation to introduce two double bonds via enol silicon ether from diketones.

A core-shell structure zirconium silicate encapsulated carbon (C@ZrSiO4) pigment was synthesized by a molten-salt assisted method. The experimental results indicated that the Na2WO4 molten-salt associated with the synthesis of ZrSiO4 at low temperature and controlled the morphology of the encapsulation pigment simultaneously. The encapsulated pigment prepared with the assistance of Na2WO4 molten-salt showed regular microcubes about 3.0 μm, while the pigment in the absence of molten-salt have serious aggregation with a particle size of 12.78 μm. Moreover, the maximum addition amount of carbon black was increased significantly from 15 wt% to 40 wt% after adding molten-salt, while the chromatic value L* of C@ZrSiO4 pigment decreased from 68.21 to 33.08 accordingly. The pigment exhibited excellent thermal stability at high temperature, making it a promising candidate for ceramic decoration.

The combination of photoredox catalysis and enamine catalysis has enabled the development of an enantioselective aerobic oxidative cross-dehydrogenative coupling between glycine derivatives and simple ketones or aldehydes, which provides an efficient approach for the rapid synthesis of enantiopure unnatural α-alkyl α-amino acid derivatives in good yield with excellent diastereo- (up to >99 : 1) and enantioselectivities (up to 97% ee). This process includes the direct photoinduced oxidation of glycine derivatives to an imine intermediate, followed by the asymmetric Mannich-type reaction with an enamine intermediate generated in situ from a ketone or aldehyde and a chiral secondary amine organocatalyst. This mild method allows the direct formation of a C–C bond with simultaneous installation of two new stereocenters without wasteful removal of functional groups., A visible-light-induced enantioselective aerobic oxidative cross-dehydrogenative coupling between glycine derivatives and simple ketones or aldehydes is achieved.

Despite the tremendous contribution of irrigated agriculture in addressing global food security, there is still confusion for farmers and governments about the choice of irrigation mode owing to the drastic environmental impacts of irrigation, including water shortage, energy crisis, and global warming. Exploring the agricultural water-energy‑carbon (WEC) nexus under different irrigation modes helps to accomplish the multi-objective of waterenergy saving and carbon emission reduction. In this paper, a conceptual framework was nominated to evaluate the waterenergy consumption and carbon emissions for winter wheat irrigation at township level and quantitatively discuss the complex interaction by the coupling coordination degree (CCD) of the WEC system under different irrigation modes in Henan Province, China. We discovered that irrigation modes profoundly affect water and energy consumption and carbon emissions in agriculture, as well as the spatial distribution of CCD from WEC system. Townships under irrigation mode with diversion and irrigation projects as the primary method (WDI) clustered together in the north and east with highest water consumption and carbon emissions, while townships under irrigation mode with rain-fed agriculture as the primary method (PI) accumulated in the west and south with lower water consumption and carbon emissions. Meanwhile, the CCD of the WEC nexus system was in basic coordination (0.40) and showed an unbalanced spatial distribution pattern with high in the southeast and low in the northwest. By comparing four irrigation modes, the coupling level of the WEC nexus system under irrigation mode with groundwater irrigation as the primary method (GI) was better and PI mode was the least ideal. This study helps to further understand agricultural WEC nexus under different irrigation modes and provide references for local governments in selecting appropriate irrigation modes to realize water-energy saving and carbon emission reduction in agricultural activities.

The COVID-19 outbreak is a manifestation of the contradiction between man and land. Geography plays an important role in epidemic prevention and control with its cross-sectional characteristics and spatial perspective. Based on a systematic review of previous studies, this paper summarizes the research progress on factors influencing the spatial spread of COVID-19 from the research content and method and proposes the main development direction of geography in epidemic prevention and control research in the future. Overall, current studies have explored the factors influencing the epidemic spread on different scales, including global, national, regional and urban. Research methods are mainly composed of quantitative analysis. In addition to the traditional regression analysis and correlation analysis, the spatial lag model, the spatial error model, the geographically weighted regression model and the geographic detector have been widely used. The impact of natural environment and economic and social factors on the epidemic spread is mainly reflected in temperature, humidity, wind speed, air pollutants, population movement, economic development level and medical and health facilities. In the future, new technologies, new methods and new means should be used to reveal the driving mechanism of the epidemic spread in a specific geographical space, which is refined, multi-scale and systematic, with emphasis on exploring the factors influencing the epidemic spread from the perspective of spatial and behavioral interaction, and establish a spatial database platform that combines the information of residents’ cases, the natural environment and economic society. This is of great significance to further play the role of geography in epidemic prevention and control.

A photoredox catalyst free, visible-light-induced aerobic oxidative [2 + 3] cycloaddition reaction between glycine derivatives and styrene oxides has been disclosed that provides an efficient approach for the rapid synthesis of 1,3-oxazolidines under mild conditions. This photoinduced process is enabled by the formation of an electron donor-acceptor complex between glycine derivatives and benzyl iodides.

CsPbX3 (X = Cl, Br, I) nanocrystals (NCs) are competitive fluorescent materials for lighting and displays owing to their excellent photophysical properties. However, the stability and optoelectronic performance of the perovskite NCs are severely limited by the highly dynamic binding feature of the present ligand strategy. Herein, a facile approach was employed to synthesize CsPbBr3 NCs with the assistance of the ionic liquid (IL) 1-butyl-3-methylimidazolium bromide ([Bmim]Br). By strictly controlling the addition dose of [Bmim]Br (nIL/nPb = 0.125) into the reaction precursor, it is possible to obtain the desired cube-shaped and monodisperse CsPbBr3 NCs with simultaneous enhancement of the storage and irradiation stability as well as photoluminescence quantum yields (PLQYs, ∼91%). Stability tests show that the emission intensity of the parent CsPbBr3 NCs drops to 50% of its initial emission intensity after storage under an open atmosphere for 91 days, while the sample prepared with the assistance of [Bmim]Br can maintain 82% of the PL intensity. Meanwhile, the modified CsPbBr3 NCs also present superior photo-stability, and still maintain 81% of the original PL intensity after continuous illumination under an ultraviolet lamp for 24 h, but the intensity of the parent CsPbBr3 NCs reduces to 35% of the original intensity. Through the morphology, composition, and luminescence kinetics evolution of CsPbBr3 NCs, these benefits were attributed to the modulation by [Bmim]Br, which could effectively provide Br ions for the formation and growth of NCs, resulting in the reduction of surface traps. Moreover, [Bmim]Br exhibited strong interactions with NCs, and the deprotonation of oleic acid (OA) was inhibited, resulting in the effective passivation of surface defects. Finally, CsPbX3 NCs with different compositions were obtained via a facile anion exchange reaction, leading to the tunable emission in the range of 462–665 nm and a wide colour gamut (129.65% NTSC standard). This work opens a new avenue for modulating the surface properties of CsPbX3 NCs, which will create opportunities for their application in the photoelectric field.

Psiguajdianone (1), a novel caryophyllene-derived meroterpenoid dimer, was isolated from Psidium guajava. The structure of 1 was determined by X-ray analysis and confirmed by total synthesis. Our synthetic strategy involves biomimetic cascade Knoevenagel condensation/hetero-Diels-Alder reaction and dimerization. Notably, the caryophyllene-derived meroterpenoids obtained during our synthesis were first identified as artifacts in the laboratory, and five of them were proven to be natural products present in the plant. Moreover, these compounds show significant anti-inflammatory activity.

Highly fluorescent Ag–In–S/ZnS (AIS/ZnS) core/shell quantum dots (QDs) with good crystallinity were synthesized via hydrothermal method with adding ZnS precursors directly into AIS cores initial solution. The influences of shell growth time and Zn/AgIn ratios on the crystal structure, composition and morphology were analyzed by using X-ray diffraction (XRD) and high-resolution transmission electron microscope (HRTEM), and the fluorescence properties of AIS/ZnS core/shell QDs were systematically investigated by absorption and photoluminescence (PL) spectra. In contrast with AIS cores, the AIS/ZnS core/shell QDs showed significantly improved yellow-orange emission with long PL lifetimes, as well as the maximum quantum yield (QY) increased from 21.6% to 45.7%. Moreover, bright white light was successfully generated from the AIS/ZnS QDs and Lu 3 Al 5 O 12 :Ce 3+ phosphors based white light-emitting diode (WLED). Under the forward bias current of 200 mA, the fabricated WLED exhibited a high luminous efficiency of 77.98 lm/W with the Commission Internationale de I'Eclairage (CIE) color coordinate of (0.32, 0.32), a color rendering index (CRI) of 85 and the correlated color temperature (CCT) of 6215 K, demonstrating the prospective application of obtained QDs in solid-state lighting devices.

Purpose This paper aims to study the temporal and spatial variation of vegetation and the influence of climate change on vegetation coverage in the Yellow River basin, China. The current study aimed to evaluate the role of a series of government-led environmental control projects in restoring the ecological environment of the Yellow River basin. Design/methodology/approach This paper uses unary linear regression, Mann–Kendall and wavelet analyses to study the spatial–temporal variations of vegetation and the response to climate changes in the Yellow River, China. Findings The results showed that for the past 17 years, not only the mean annual increase rate of the Normalized Difference Vegetation Index (NDVI) was 0.0059/a, but the spatial heterogeneity also yields significant results. The vegetation growth in the southeastern region was significantly better than that in the northwestern region. The variation period of the NDVI in the study area significantly shortened, and the most obvious oscillation period was half a year, with two peaks in one year. In addition, there are positive and negative effects of human activities on the change of vegetation cover of the Loess Plateau. The project of transforming cultivated land to forest and grassland promotes the increase of vegetation cover of the Loess plateau. Unfortunately, the regional urbanization and industrialization proliferated, and the overloading of grazing, deforestation, over-reclamation, and the exploitation and development of the energy area in the grassland region led to the reduction of the NDVI. Fortunately, the positive effects outweigh the negative ones. Originality/value This paper provides a comprehensive insight to analysis of the vegetation change and the responses of vegetation to climate change, with special reference to make the planning policy of ecological restoration. This paper argues that ecological restoration should be strengthened in areas with annual precipitation less than 450 mm.

Monoclinic bismuth vanadate (m-BiVO4) yellow pigments were synthesized by non-hydrolytic sol-gel (NHSG) route without any surfactants. The presence of Bi–O–V band in the sol and xerogel, indicates that the excellent atomic scale homogeneity could be reached. It is beneficial to achieve high purity m-BiVO4 phase and submicron scale particles (738 nm) with homogenous distribution at low temperature (400 °C), resulting in a brilliant yellow hue (b* = 71.18, hab = 89.73). These pigments have better chromatic performance than previously reported and commercially available BiVO4 yellow pigments. Meanwhile, the cytotoxicity of the pigment was tested in Mus musculus skin melanoma cells, and showed nontoxic for human cells, indicating its potential application in the high quality paints for automotive and architectural finishes.

Capitulactones A-C, three unprecedented 9-norlignans featuring a unique 3,5-dihydrofuro[2,3- d]oxepin-7(2 H)-one scaffold, were isolated from the roots of Curculigo capitulata. Their structures with absolute configurations were unambiguously established by a combination of spectroscopic data, ECD analysis, and total synthesis. Biomimetic total syntheses of three pairs of the corresponding enantiomers were achieved in 9-10 steps with overall yields of 14.8, 12.7, and 10.3%, respectively. Notably, the unique scaffold of the common western hemisphere of the molecules was constructed by using the oxidation-reduction strategy from benzodihydrofuran.

The first gram-scale asymmetric total synthesis of (+)- and (-)-codonopiloneolignanin A has been achieved from multisubstituted cinnamaldehyde in four steps with 37% overall yield. The synthetically challenging tricyclic [5, 3, 0, 03,8] decane skeleton was efficiently constructed via a highly enantioselective dimerization of multisubstituted cinnamaldehyde, followed by a sequence of cascade reactions including Prins cyclization, cation mediated cyclization, and deprotection. Furthermore, the scope of NHC-catalyzed/Ti(IV)-mediated synergistic control multisubstituted cinnamaldehyde dimerization was investigated. Significantly, the bioactivity of codonopiloneolignanin A and its enantiomer, particularly scarce in nature, was tested and showed good anticancer activity.

Plant derived carbon was utilized as a new financial and environmental friendly colorant in the synthesis of zircon encapsulated carbon pigment (C@ZrSiO4) via non-hydrolytic sol-gel method. After calcining, nature plants, i.e. sisal and bamboo leaves, were carbonized and occluded in ZrSiO4 matrix. The FT-IR and XRD results demonstrated that the plants were not affect the non-hydrolytic sol-gel polycondensation reaction, resulting in the pure ZrSiO4 formation. Both inclusion pigments presented deep black hue, i.e. L∗ = 34.93 and 33.02 for sisal and bamboo leaves, respectively, which was contributed to the homogeneous pore-size distribution and high carbon yield of the plants. These pigments have many distinguished advantages including low cost, high chromatic performance and excellent thermal stability, making them promising candidates for ceramic decoration.

A facile approach towards photoluminescent (PL) Cu-In-Zn-S quantum dots (CIZS QDs) has been developed, comprising microwave treatment with the assist of room-temperature ionic liquid (RTIL). Because of its high polarizability, RTIL served as a microwave absorbent, which resulted in the increase of the instantaneous nucleation rate and the rapid synthesis of CIZS QDs at low temperature. Moreover, the surface decoration of QDs with RTIL can passivate the surface defects greatly. The PL intensity of the CIZS QDs depends on the anion species, alkyl chain length of the RTIL, and the metal element ratios of the QDs. On the basis of the variable PL peak position and extended luminescence lifetime of the CIZS QDs, the superior emission behavior of the QDs was confirmed by surface etching with fluoride produced by the hydrolysis of RTIL 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim]BF4 ). Moreover, the intermediate alkyl chain length of the RTIL can avoid aggregation, which results in the construction of CIZS QDs with homogenous size distribution. The shape-controlled CIZS QDs show a broadened tunable emission peak from 677 to 579 nm compared with that of QDs prepared by a conventional one-pot method by mixing the raw materials. CIZS QDs also exhibit a high quantum yield (QY) of 24.1 % after coating with a ZnS shell. This method is expected to be a useful technique for the rapid synthesis of multiple QDs with a wider range of emission wavelengths and higher QY for a variety of applications.

Yellow inorganic pigments PrxZr1-xSiO4 (x = 0–0.08) have been prepared by a novel non-hydrolytic sol-gel (NHSG) method at 750 °C for 2 h. Replacing Pr4+ for Zr4+ in ZrSiO4 increased the cell volume and changed the color from white to yellow gradually. The Si―O―Zr and Si―O―Pr bands were observed in the FT-IR spectra of xerogel, indicating it could reach homogeneous mixing at the atomic level. Therefore, it promoted the solid solution reaction between Pr and zircon at low temperature. The samples exhibit high doping limitation (x = 0.08) and brilliant yellow hue (b* = 69.48) in contrast with the previously reported praseodymium zircon yellow pigments. The intense of yellow hue was increased with increasing the Pr doping content due to the increase of Pr4+/Pr3+ species. After applying on bisque ceramic tiles, the pigment exhibited excellent coloration, high thermal stability and low solubility in molten glazes, indicating its potential application in ceramic decoration.

BACKGROUND Whey acidic protein/four-disulfide core domain 21 (Wfdc21), also known as Lnc-DC, it has been reported to be correlated with immune response. However, the role of Wfdc21 in the pathogenesis of sepsis is still unknown. In the present study, we aimed to investigate the role of Wfdc21 in the pathogenesis of sepsis. MATERIAL AND METHODS The cecal ligation and puncture (CLP)-induced sepsis model was established in Balb/c mice. Animals were euthanized 4, 8, 16, or 24 h after CLP. The glycogen distribution in the kidney and liver was checked by Periodic acid-Schiff (PAS) staining. Changes in the serum interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) concentrations were monitored with ELISA, and Wdfc21 expression was determined by qPCR. Mouse macrophage-like RAW264.7 cells were treated with different doses of lipopolysaccharide (LPS) from Escherichia coli to mimic sepsis in vitro. Western blot analysis was performed to confirm whether LPS-induced in vitro sepsis was correlated with the involvement of the Stat3/TLR4 signaling pathway. In addition, RAW 264.7 cells were infected with lentiviruses containing Wfdc21 shRNA to further confirm the role of Wfdc21 in the pathogenesis of sepsis. RESULTS We found that Wfdc21 level was elevated in the CLP-induced animal model and LPS-treated RAW264.7 cells. Furthermore, the downregulation of Wfdc21 modulated the concentration of pro-inflammatory factors in LPS-treated macrophages, such as IL-1β and TNF-α, in LPS-treated macrophages. This regulatory effect was mediated through the Stat3/TLR4 signaling pathway, since Wfdc21 can regulate p-Stat3 and TLR4 levels in LPS-treated macrophages. CONCLUSIONS Wfdc21 plays a critical role in the pathogenesis of sepsis and may provide a therapeutic target for sepsis treatment.

Concise total syntheses of callistrilones A-E have been achieved from 7 and commercially available α-phellandrene (8). The synthetic strategy, which was primarily inspired by the biogenetic hypothesis, was enabled by an oxidative [3 + 2] cycloaddition followed by a Michael addition and an intramolecular nucleophilic addition to construct the target molecules. Moreover, viminalin I was also synthesized, and its absolute configuration was unambiguously confirmed.

Polymer spheres with tunable particle size were synthesized by hydrothermal method derived from sucrose. Afterwards, zircon was coated on their surface to form the zircon encapsulated carbon (C@ZrSiO4) black pigment after calcination. The corresponding relationship between the particle size of polymer spheres and the chromaticity of C@ZrSiO4 pigments was investigated. The results revealed that the chromatic performance of C@ZrSiO4 pigment can be significantly improved by decreasing the colorant size and the relationship between them was approximately linear. The pigment exhibits deep black hue, as L∗ = 41.04, a∗ = 1.01, b∗ = 3.22, with the colorant size of 123 nm. Moreover, it also presents excellent thermal and chemical stability, indicating its potential candidate for ceramic decoration.

Salyunnanin A and hassanane, two C23 terpenoids, were achieved from (+)-carnosic acid in 6 and 5 steps, respectively. The synthetic strategy was primarily inspired by the biogenetic hypothesis and provided access to the natural products via elimination, double Michael-type addition in one pot to prepare the corresponding 6,20-epoxyabietanes, and bismuthonium ylide induced ring expansion of o-quinone to construct 2-acyl-3-hydroxytropone.

A concise total synthesis of myrtucommulone K, N and O have been developed in 4 steps from commercially available materials. The synthetic strategy was inspired primarily by the biogenetic hypothesis and firstly enabled via a reduction, dehydration sequence for preparing isobutylidenesyncarpic acid followed by a hetero-Diels-Alder reaction to disclose the target moleculars. In this approach the exocyclic double bond of (−)-β-caryophyllene was more active than the endocyclic one in hetero-Diels–Alder reaction as the dienophile. The route is protecting-group-free, concise step, redox and pot economy.

This paper presents an optimal NARX neural network identification model for a magnetorheological (MR) damper with the force-distortion behavior. An intensive experimental study is conducted for designing the NARX network architecture to enhance modeling accuracy and availability, and the activation function selection, weights and biases of the selected network are optimized by differential evolution algorithm (DEA). Different experimental training and validation samples are used for network training. The prediction capability of the optimal NARX model is verified by new measured test data. The test and comparative results show that the optimal NARX network model can satisfactorily emulate the dynamic behavior of MR damper and effectively capture its distortion behavior occurred with the increased current. The developed inverse NARX network model can effectively estimate the required current and track desired damping force. Moreover, the effects of different noise disturbance on the NARX network model performance are analyzed, and the model error varies slightly with a small noise disturbance. The accuracy of the results supports that the use of this modelling technique for identifying irregular nonlinear models of MR damper and similar devices.

The 400 mm annual precipitation fluctuation zone (75°55′–127°6′E and 26°55′–53°6′N) is located in central and western China, which is a transition area from traditional agricultural to animal husbandry. It is extremely sensitive to climatic changes. The corresponding changes of the ecosystem, represented by vegetation, under the dual influences of climate change and human activities are important issues in the study of the regional ecological environment. Based on the Savitzky–Golay (S–G) filtering method, the Global Inventory Modeling and Mapping Studies (GIMMS) Normalized Differential Vegetation Index (NDVI) dataset (NDVI3g) was reconstructed in this paper. Sen’s slope estimation, Mann–Kendall (M–K), multiple regression residual analysis, and the Hurst index were used to quantify the impacts of climate change and human activities on vegetation; in addition, the future persistence characteristics of the vegetation changes trend were analyzed. Vegetation changes in the study area had an obvious spatio-temporal heterogeneity. On an annual scale, the vegetation increased considerably, with a growth rate of 0.50%/10a. The multi-year mean value of NDVI and growth rate of cultivated land were the highest, followed by the forest land and grassland. On a seasonal scale, the vegetation cover increased most significantly in autumn, followed by spring and summer. In the southeastern and central parts of the study area, the vegetation cover increased significantly (P < 0.05), while it decreased significantly in the northeastern and southwestern parts. In summer, the NDVI value of all vegetation types (cultivated land, forest land and grassland) reached the maximum. The change rate of NDVI value for cultivated land reached the highest in autumn (1.57%/10a), forest land reached the highest in spring (1.15%/10a), and grassland reached the highest in autumn (0.49%/10a). The NDVI of cultivated land increased in all seasons, while forest land (−0.31%/10a) and grassland (−0.009%/10a) decreased in winter. Partial correlation analysis between vegetation and precipitation, temperature found that the areas with positive correlation accounted for 66.29% and 55.05% of the total area, respectively. Under the influence of climate change alone, 62.79% of the study area showed an increasing tendency, among which 46.79% showed a significant upward trend (P < 0.05). The NDVI decreased in 37.21% of the regions and decreased significantly in 14.88% of the regions (P < 0.05). Under the influence of human activities alone, the vegetation in the study area showed an upward trend in 59.61%, with a significant increase in 41.35% (P < 0.05), a downward trend in 40.39%, and a significant downward trend in 7.95% (P < 0.05). Vegetation growth is highly unstable and prone to drastic changes, depending on the environmental conditions.

Synthesis of water-soluble I-III-VI type quantum dots (QDs) with high luminescence performance in efficient pathways still remains a tremendous challenge. In this study, water-soluble Ag-In-Zn-S (AIZS) QDs were prepared via the room temperature ionic liquids (RTILs) assisted hydrothermal method. The experimental results showed that the RTIL 1-methylimidazolium tetrafluoroborate ([Mim]BF4) played an important role in the phase structure, morphology, and optical properties of the AIZS QDs due to its high polarity and low surface tension, which was beneficial to the nucleation, growth, and surface modulation of QDs, resulting in the improvement of quantum yield (QY) from 23.2% to 28.9%. Moreover, the AIZS QDs exhibited long fluorescence lifetimes of 472.3 ns, further demonstrating the successful passivation of the trap states of QDs. Furthermore, the emission wavelength of AIZS QDs could be adjusted from 608 to 525 nm by tuning Ag/Zn ratios. Finally, a white light-emitting diode (WLED) based on AIZS QDs and green Lu3Al5O12:Ce3+ phosphor was successfully fabricated, which showed high luminous efficiency of 85.2 lm/W, color rendering index (CRI) of 62.2, and the correlated color temperature (CCT) of 6153 K, indicating the promising prospects of AIZS QDs’ application in photoelectric devices.
