摘要：

Herein, we report a new set of white-emitters i.e., BaLa2ZnO5:Dy3+ nanomaterials, fabricated via an inexpensive and energy-saving urea-aided-combustion route. Tetragonal phase-transparency had been authorized via X-ray powder diffraction-facilitated-Rietveld refinement analysis. Under 355 nm energization, target samples manifested white-luminance via two bands, namely bluish and golden (485 & 578 nm). Fine photometric characteristics of optimal nanopowder had been reflected in white coordinates (0.2693, 0.3278) with high purity of white-light (27.61 x 10-2), quantum-efficiency (74.95%), and appropriate color-temperature (9290 K). Briefly, the aforementioned results suggested their promising employment for generating cool-white-light in highperformance cool-wLEDs (white-light emanating diodes), lasers, indoor-cultivation, sensors, and photovoltaiccells.
