摘　　要：激光二极管(LDs)结合荧光转换材料实现白光被认为是下一代照明光源,其中的荧光转换材料对于整体光源的光度/色度参数、发光效率、长期工作稳定性至关重要。近年来,人们在LD照明中采用多种绿/黄/红荧光材料来丰富光谱成分,获得高质量的白光。其中,采用Lu_(3)Al_(5)O_(12)∶Ce^(3+)(LuAG∶Ce^(3+))绿色荧光材料作为主体成分,结合光谱展宽、红光补足等方案可将LD照明白光的显色指数大幅度提升。LuAG∶Ce^(3+)被认为是综合性能最优的绿色转换材料之一,在大功率LD的辐照下具有很高的热稳定性和饱和阈值。本文主要对基于LuAG∶Ce^(3+)的荧光晶体、荧光陶瓷、荧光玻璃、荧光薄膜等形态材料的制备方法及其在LD照明中的应用性能研究进行了总结,并且对其未来发展方向提出了展望。Laser-diodes(LDs)combined with color converters are regarded as the next-generation lighting source.Color converters play important roles in determining the luminous efficiency,color quality,and long-term stability of the LDs lighting.Recently,kinds of green/yellow/red color converters were adopted to enrich spectral components and achieve a high color quality in the LDs lighting.Among them,the color rendering index of the LDs lighting can be greatly improved by using Lu_(3)Al_(5)O_(12)∶Ce^(3+)(LuAG∶Ce^(3+))and red color converters.LuAG∶Ce^(3+)is regarded as one of the best green color converters.It has high thermal stability and saturation threshold under high-power LDs.To mitigate the thermal effect induced by the high-power density of blue LDs,remote encapsulations of single-crystal phosphors,(transparent)ceramic phosphors,phosphor in glasses/films are proposed.This paper reviews and summaries recent progress of LuAG∶Ce^(3+)for LD lighting application and puts forward the prospect of the future development direction.
