Generation of cost-effective conventional-combustion derived novel green-luminous BaLa2ZnO5:Er3+ nanomaterials for high quality illumination in WLEDs and solar-cells

Abstract

In the current empirical-study, novel green-glimmering BaLa2ZnO5:Er3+ nanomaterials have been fabricated via conventional-combustion-synthesis. XRPD-facilitated Rietveld-analysis report tetragonal nanocrystals with 14/ m c m phase-group. Photoluminescence analysis manifest their green-radiance under 383 nm-excitation. Best luminance has been attained at x = 0.03 Er3+-content. Quantum-efficiency and color-purity of optimal sample has been reckoned as 84.74 and 83.75%, respectively. Excellent luminescent profile is reflected in green color-coordinates (0.2404, 0.5692) and 7366 K color-temperature, which have been contiguous to standard TV, SD-color, European-Broadcasting-Union and NICHIA-LED green-coordinates. All-in-all, these comprehensive results insinuate their optimistic candidacy for advanced-WLEDs, sensors, solar-cells, optical-switches, bio-imaging and photonic applications.
