摘要

采用高温固相法合成了Nb,5+,、Sm,3+,共掺杂YTaO,4,长余辉发光材料，通过X射线粉末衍射（XRD）、稳态荧光光谱、漫反射光谱和热释光曲线等多种表征手段研究了材料的结构、荧光和长余辉发光特性。XRD结果表明，共掺杂Nb,5+,和Sm,3+,没有引起YTaO,4,晶体结构的改变。光谱分析表明，共掺Nb,5+,不仅可大幅提高YTaO,4,中Sm,3+,的长余辉发光强度，而且可实现长余辉发光颜色的调控。对Sm,3+,和Nb,5+,共掺杂调控长余辉发光特性的机理也进行了分析。

Abstract

The Y,0.98,Sm,0.02,TaO,4, long lasting phosphorescence(LLP) material was synthesized by high temperature solid state reaction, and the co-doping experiment of replacing Ta,5+, with Nb,5+, was also carried out. The results of X-ray powder diffraction spectra shown that the doped ions did not change the crystal structure of YTaO,4,. Through room temperature steady-state photoluminescence(PL) and long-lasting phosphorescence experiments, it is found that the addition of Nb,5+, can greatly increase the intensity of long-lasting phosphorescence of Sm,3+, in YTaO,4, and change the emission color of PL and LLP. In this paper, the properties and mechanism of PL and LLP of YTaO,4,:Sm,3+, Nb,5+, are studied, respectively.
