白光LED作为第四代照明光源已经广泛应用到人们生活的各个领域,其中荧光粉是获得高性能白光LED的关键材料之一。如何用简单的方法制备高性能的荧光粉是目前研究人员的一个挑战性工作。本文采用高温固相法,加入助熔剂h_(3)BO_(3)、Nh_(4)Cl、Sr._(2)、LiF和Ba._(2),成功制备了Ba.l_(4)Sb_(2)O_(12)∶Eu^(2+)(Ba.O∶Eu^(2+))荧光粉。通过晶体结构分析、发射光谱、X射线光电子能谱(XPS)以及荧光寿命分析,表明过量的Sb_(2)O_(3)能够有效地将Eu^(3+)还原成Eu^(2+),提高Eu^(2+)在563 nm处的荧光强度约12.5倍,内量子效率(IQE)可以达到96.14%。另外,还研究了不同助熔剂对荧光粉晶体结构、荧光强度以及内量子效率的影响。本实验采用的方法简单,避免使用具有一定危险的还原性气体烧结,易于工业化应用以及降低生产成本。
