Fabrication of low-temperature Ce3+:YAG doped glass for phosphor-converted white-light-emitting diodes

Fabrication of low-temperature Ce3+:YAG doped glass for phosphor-converted white-light-emitting diodes

The optical characteristics of LTCeYDG applied to high-power PCWLEDs are demonstrated. The LTG powder exhibited a lower transition temperature about 567°C. The 4-wt% LTCeYDG, distribution uniformity and quantum efficiency were measured 85% and 34.5%, respectively.
