Abstract

The glass samples (35-x)B2O3:35SiO2:12Na2O:7.9CaO:0.1Sb2O3:10BaO:xCr2O3 with a variation of Cr2O3 content were successfully fabricated and characterized for solid-state lighting material applications. The results showed the most suitable composition within the range of study at 0.02 mol% of Cr2O3. This composition gave higher reflection loss (RL), lower oxide polarizability, and lower molar refractivity. The Commission International de I'Eclairage (CIE) chromaticity coordinates confirmed a strong orange color emission. Hence, this suggests that the 0.02 mol% Cr2O3 glass is a good candidate and cost-effective for orange-emitting solid-state lighting material applications. This study will be a useful literature source for further development in this field. ฉ 2023 Taylor & Francis Group, LLC.
