由于目前LED用绿色荧光粉体系分别存在热稳定性差、显色指数低、制备复杂苛刻等问题,因此日本三菱化学开发出了一种新型LED用绿色Ca3Sc2Si3 O12:Ce3+钪硅酸盐荧光粉.在综述Ca3 Sc2Si3 O12:Ce3+荧光性能的基础上,总结分析了Ca3Sc2Si3O12:Ce3+荧光发光材料的晶体结构和发光机制,表明这种荧光粉兼备了硅酸盐和YAG:Ce荧光粉的石榴石结构,使得晶体场能够与Ce3+配合展现出良好的匹配性,可以很好的与现行蓝光芯片匹配得到高品质的白光,并且类似YAG晶体的石榴石结构有着良好的发光性能和热稳定性;讨论了在电荷补偿作用和这种作用下基质改变后荧光粉的性能变化,以及激活剂改变、能量传递的影响,表明荧光粉光色可调幅度较大,能够根据不同变化产生不同的发光;然后分固相法和液相法总结了该荧光粉的制备方法,证明该荧光粉烧结温度低、合成工艺适应性广泛,并且高温固相法是工业化生产该系列荧光粉的最佳方法;最后展望了Ca3 Sc2 Si3 O12:Ce3+荧光转换材料的发展趋势和在白光LED中的应用前景,作为一种新型高效的白光LED用绿色荧光粉,需要进一步的研究和探索.
