Our present technological society needs the assistance of lanthanide luminescence in almost every field to meet the global energy demands. In present research work we have synthesized five (one binary and four ternary) 5-(4-methylphenyl)-2- furoic acid based Eu(III) complexes with ancillary ligands, namely, aqua (H

Single-phase nanomaterials are the most promising materials, owing to their high luminous-efficiency, environmental-friendly and multicolor-luminance features. The crystal structure of Eu3+/Tb3 + co-doped SrLaAlO4 (SLAO) nanopowders were developed by combustion synthesis (CS). The formation of SLAO materials with tetragonal space group 14/mmm (1 3 9) was confirmed by Rietveld refinement of X-ray diffraction (XRD) arrangement. Multicolor luminescence has been achieved via tailoring Tb3+/Eu3+ ratio into SLAO matrix, under UV and near-UV irradiation. Moreover, energy-transfer (ET) efficiencies and analogous mechanisms have been discussed deeply. This work opens avenues for scholars to explore such nanomaterials for advanced photonic applications like white-LEDs, solar-cells, lasers, photo-detectors, etc.

Dud-white emanation from current phosphor-based white-LEDs (pb-WLEDs) has now emerged as primary gridlock for their commercialization. Thus, coupling of green–blue-red (G-B-R) multi-phase or white single-phase phosphors with near-UV LED chips, clarifies such snags. Heeding the innovative solution, the authors have successfully manufactured novel Sr5Al2O8:Sm3+, Er3+ and Dy3+, via adopting a propitious urea combustion approach. Photoluminescence spectra realized the remarkable orange (599 nm), green (548 nm) and near-white (575 nm) emission. Thereafter, laudable colorimetric performance of nanomaterials with improved color-coordinates, color purity & CCT, suggest their promising usage in photonic appliances like pb-WLEDs, bio-probes, solar cells, telecommunication, lasers and optical sensors.
