摘要

首次报道了纳米YPO

粉末材料的化学制备方法和光谱特性

结构分析证实共沉淀法制得的样品为粒径20nm的纳米微晶。对激发Pr

离子

能级下的光谱性能进行了测量

同在体材料中一样

得到了来自较高能级

强发射。研究表明这是由不同Pr

Abstract

The chemical preparation method and spectrum characteristics of YPO

:Pr

nanocrystal powder are reported for the first time. The structure analysis shows that the sample is nano material with radius of about 20nm. A strong emission from

level of Pr

ion is observed under excitation at

level by a Ar

laser set at 488nm. This is caused by the efficient cross relaxation energy transfer of {

} between different Pr

ions.
