Luminescence tuning and structural analysis of new BaYAlZn3O7:Sm3+ nanomaterials with excellent performance for advanced optoelectronic appliances

The present prospective observational study reports the generation of new Sm 3+ -incorporated BaYAlZn 3 O 7 nanomaterials via urea-combustion route. Rietveld facilitated XRPD (X-ray powder diffraction) analysis outlines the absolute hexagonal phase in the nano-crystalline powders. Photo-luminescence (PL) technique reports the intense-orange–red emission, centered at 708 nm maximum. Higher content of Sm 3+ retards the PL life-time and intensity, such that x = 0.02 is the best luminance composition. Post it, luminance quenching has been ascertained, which is attributed to the exchange type inter-linkages, as affirmed via Inokuti–Hirayama and Dexter’s model. Also, various radiative-possessions including decay-time (2.4876 ± 0.0311 ms), intrinsic life-time (3.4380 ms), quantum-efficiency (72.36%) and relaxation-rate (0.1111 ms −1 ), which reflect their better luminance-potentiality, have been evaluated. Color-coordinates (0.5299, 0.4670) for the same phosphor have realized their intense-orange radiance, which are proximate to those (0.570, 0.420) illustrated via AMBER LED-NSPAR 70 BS (generated via NICHIA CORP.). All the crystallographic and optical properties of the phosphor-powders, thus, vividly define their potential usage in near-ultra-violet triggered white-light-emitting diodes, digital-signs, horticulture, bio-imaging, solar-cells, lasers, and other optoelectronic appliances. Also, all the reported outcomes will certainly open an avenue for researchers to design more BaYAlZn 3 O 7 -like materials.
