Resumo

A transparent Ce3+: Y3Al5O12 (Ce: YAG) glass ceramic with high quantum yield of 94% and improved thermal-quenching feature, using low-cost Sb2O3-based glass as host, is developed to replace the conventional phosphor/organic-resin color converter. The constructed glass–ceramic-based white-light-emitting diode exhibits a high luminous efficiency of 130 lm/W, superior to that of the conventional pc-WLED (95 lm/W), and a correlated color temperature of 5298 K as well as a color rendering index of 65, which reveal the prominent feasibility of the present glass ceramic material in high-power organic-resin-free WLED application.
