Robust YAG∶Ce single crystal for ultra-high efficiency laser lighting
文献摘要：
At present,solid-state laser-driven lighting fabricated with blue laser diode(LD)and phosphor has been greatly developed in high-power lighting applications.The major obstacle is the luminescence saturation threshold of the fluorescence conversion material(YAG∶Ce).In this work,we successfully prepared a series of high-quality and robust YAG∶Ce single crystals.With high quantum efficiency(QE=92％),regular crystal structure and high thermal conductivity,the single-crystal has excellent ability to deal with high radiation flux and thermal accumulation generated by high power.Matching the single-crystal with the laser,the luminous efficiency up to 274 Im/W and saturation threshold of 12 W/mm2 were obtained.In addition,the influence of Ce doping concentration and sample processing conditions on the indicators in laser-driven white lighting was systematically studied.The results are of great significance and are believed to promote the development of solid-state laser-driven lighting.
