综述了单基质全色荧光粉的研究进展,重点评述了近年来新出现的单基质两基色或三基色白光发射体系,如Ce3+/Eu2+共激活的硼酸盐、氯铝酸盐等两基色体系,Eu2+/Mn2+共激活的氯硅酸盐、硼磷酸盐等三基色体系;同时分析该类材料及其应用的研究现状和发展方向。
A review of research of single phase white light emitting phosphor for light conversion white light emitting diode(LED) are presented,focusing on single-phase two-or three-color white light emitting systems,such as the Ce3+/Eu2+ co-doped chloro-aluminate or borate two-color system and the Eu2+/Mn2+ co-doped chloroilicate or borate-phosphate three-color system.Moreover,application research and developments of these phosphors are also analyzed.
