The study provides a unique approach for controlling the structural, electrical, optical, and photoluminescence characteristics of oxostannate Cs2Sn2O3 (C2T2O3) nanostructures through the process of co-precipitation. XRD, XPS, Raman, HRTEM, and FESEM techniques were employed to investigate and describe the impact of varying annealing temperatures on a specific system. The diffraction patterns indicate the existence of an orthorhombic oxostannate C2T2O3 phase, wherein as the temperature rises, the size of the crystallites grows. Additionally, it is important to acknowledge that the spectra of Cs 3d, Sn 3d, and O 1s demonstrate the formation of materials without alteration in the position of their primary peaks when exposed to variations in temperature. Under the influence of annealing temperature, the real components of permittivity and electrical conductivity demonstrate superior characteristics in terms of frequency dependence. The optical band gap for the as-prepared C2T2O3 decreased with annealing at temperatures of 600 °C and 900 °C to 3.8 eV and 3.7 eV, respectively. The photoluminescence (PL) emission bands' positions and intensities demonstrate a significant level of sensitivity towards the existence of interstitial Cs-Sn defects. The electrical performance and luminescence emissions of nanostructured C2T2O3 systems are promising, offering a wide range of sensitivity for energy storage, optoelectronics, and luminescence applications.

Pure nanostructured thin films of nickel stannite (NiSnO3; NSO) semiconducting oxide are synthesized by a simple pulsed spray pyrolysis technique on glass substrates at different deposition temperatures and spray times. XRD recorded patterns exhibit a polycrystalline nature for the deposited films. The Raman spectra provide confirmation of the presence of Sn–O and Ni–O bands. FESEM demonstrates a membrane-like structure with hexagonal pores' formation and different diameter sizes. The NSO energy bandgap is calculated to be 3.72 eV using the absorption spectrum fitting method. The photoluminescence intensities of NSO films were found to fluctuate with the influence of deposited substrate temperature and spray time. The photo-sensing performance was examined by calculating the change in the resistance of the deposited films corresponding to the UV light exposure at room temperature. NSO samples prepared at high substrate temperatures, and long spray times perform the best dynamic photo-response for the UV illumination. [ABSTRACT FROM AUTHOR]

Facile assembly, co-precipitation, and drop casting procedures have been used to construct SnO2/SrSnO3/Fe3O4/PVDF flexible nanocomposites. SnO2/SrSnO3/Fe3O4 nanocomposites (TSF NCs') have been successfully incorporated into polyvinylidene fluoride polymers (PF), according to the microstructural exploration of the systems, which was revealed by XRD, EDX, and ATR-FTIR analysis. The FESEM and cross-section areas demonstrated that the addition of TSF NCs' to PF porous material enhanced its surface characteristics and decreased its surface roughness. The optical gap was lowered from 3.90 to 3.07 eV, and it was discovered that both the refractive index and optical conductivity had improved when TSF NCs' were incorporated into PF. According to the observations, the supplement ratios have a profound influence on the dielectric properties of the nanocomposites. Moreover, the electrical parameters of TSF/PF nanocomposite are significantly modified. The TSF/PF magnetic nanocomposite has good magnetic reactivity and can be easily extracted from the aqueous solution using an external magnetic field, as demonstrated by VSM. This research has been conducted to obtain TSF/PF nanocomposites to be used in promising magno-optoelectronic applications. [ABSTRACT FROM AUTHOR]
