摘要

利用水热法分别合成了Ce3+、Tb3+共掺杂的YPO4下转换荧光粉和Er3+、Yb3+、Tm3+共掺杂的YPO4上转换荧光粉, 经过工艺优化获得了1 μm左右尺寸均匀的发光材料。通过系列实验研究了反应温度、反应时间、稀土离子掺杂比例和退火温度对样品发光性能的影响。YPO4∶Ce3+,Tb3+荧光粉在295 nm紫外光的激发下产生下转换发光效应, 当Tb3+摩尔分数为1%时得到明亮的绿光; YPO4∶Er3+, Tm3+, Yb3+荧光粉在980 nm近红外光激发下产生上转换发光效应, 当稀土离子中Er3+摩尔分数为3%时, 所制备的样品经过1 000 ℃退火处理后发出很强的暖白光。

Abstract

Ce3+, Tb3+ co-doped YPO4 down-conversion phosphors and Er3+, Tm3+, Yb3+ co-doped YPO4 up-conversion phosphors were synthesized by using hydrothermal method. Uniform-sized (~1 μm) luminescence materials were gained through process optimization. A series of experiments were carried to study the effect of reaction temperature, time, annealing temperature and doping ratio of rare-earth ions on luminescence properties. The down-conversion luminescence nano-material YPO4∶Ce3+,1%Tb3+ emits strong green light excited by 295 nm ultraviolet light, and the up-conversion nano-material YPO4∶3%Er3+, Tm3+, Yb3+ emits warm white light excited by 980 nm infrared light, respectively.
