摘要：
High-power, high-brightness laser lighting technology put forward new requirements for the service stability of color conversion materials. Phosphor-in-glass materials (PiGs) have emerged with their unique advantages of withstanding high power excitation density. High luminous efficiency (LE) and high internal quantum efficiency (IQE) LuAG:Ce PiG is still an urgent demand for high power laser lighting conversion materials. In this paper, LuAG:Ce PiGs was successfully prepared by careful design of glass matrix composition. The maximum internal quantum efficiency of LuAG:Ce PiG is 93.8%. The conversion efficiency (CE) of LuAG:Ce PiG from blue to green light is increased to 56.3%. The luminous efficiency (LE) even reaches 225 lm W-1 , which is the best performance of LuAG:Ce in LD lighting so far. These results show that this work has taken a big step in improving the performance of LuAG:Ce Green converter and will greatly promote the development of LD lighting. (C) 2021 Elsevier B.V.
