摘要

采用溶胶-凝胶法制备了含有不同Yb

掺杂浓度的BaGd

ZnO

上转换发光材料

测量了这些样品在不同激发光密度下的上转换光发射功率及上转换效率。实验结果表明:在不同激发光密度下

所有样品的光发射功率都存在极大值

其中Yb

掺杂摩尔分数为4%

掺杂摩尔分数为1%时样品的最大发射光功率可达20 mW;样品的上转换绝对效率也存在极大值

随着Yb

和Er

浓度增加

绝对效率的极大值向较低激发光密度方向移动

在Yb

掺杂摩尔分数为9%

掺杂摩尔分数为3%时样品的上转换效率达到最高

绝对效率为3.2%

极值效率最大值为6.9%。

Abstract

BaGd

ZnO

phosphors with different doping concentrations of Yb

were prepared by using the sol-gel method. Up-conversion fluorescence powers and efficiencies were measured under different excitation density. The obtained data show that each sample has a maximum value in emission power. Among those sample

the sample of doping Yb

(4%)

(1%) has the highest power of 20 mW. Each sample had a maximum value of up-conversion absolute fluorescence efficiency. This value shifts to the lower exciting density with the increasing content of Yb

and Er

. The highest efficiency is 3.2% for Yb

(9%) and Er

(3%) sample

and the highest fluorescence efficiency is 6.9%。
