用高温固相法合成了颜色可调的SrMoO4：xEu3＋,yTb3＋荧光粉,并对其发光粉结构及其发光特性进行了研究。结果表明,SrMoO4：xEu3＋,yTb3＋荧光粉属于四方结构。Eu3＋离子在SrMoO4晶体中形成峰值为617 nm的5d→4f跃迁发光,Tb3＋离子的5 D4→7 F5跃迁产生548 nm的绿光发射。两个发射带的激发光谱范围位于250～450 nm处,SrMoO4：xEu3＋,yTb3＋在紫外、近紫外波段内有很强的激发,是一种适合InGaN芯片激发的白光LED用荧光粉。

The SrMoO4：xEu3＋,yTb3＋ phosphors was synthesized by high temperature solid state reaction.The structure and photoluminescence properties of this phosphor were investigated.The results showed that the structure of SrMoO4：xEu3＋,yTb3＋ phosphors was the tetragonal crystal structure.The emission bands of this phosphor peaked at 617 nm and 548 nm were originated from 5d→ 4f transition of Eu3＋and 5D4→7F5 transition of Tb3＋,respectively.Our color-tunable phosphors could be used in the application of white-light-emitting diode by the UV LED phosphor technology.
