摘要

通过控制Dy

的掺杂浓度

制备出了不同浓度的Eu

单掺和共掺高硅氧发光玻璃

测试其激发和发射光谱

讨论了Dy

浓度对Eu

共掺样品发光性质的影响。结果表明

共掺高硅氧发光玻璃中存在Dy

向Eu

的无辐射能量传递现象

且Dy

的引入会使高硅氧发光玻璃中Eu—O的共价作用减弱

造成Eu

发射峰蓝移;随着Dy

浓度的增加

→Eu

能量传递增强

发光增强;Dy

含量继续增加

则Dy

发光出现浓度猝灭

且Dy

→Eu

能量传递减弱。

Abstract

doped

doped and Eu

co-doped high silica luminescence glasses were prepared. By controlling the doping concentration of Dy

the different mole ratios of Dy

to Eu

were researched. The effect of Dy

on luminescence properties of Eu

co-doped high silica glass was studied by means of excitation and emission spectra. The results show that nonradioactive energy transfer from Dy

to Eu

occurred in Eu

co-doped high silica glass. By co-doping with Dy

the covalent strength of the Eu-O bond weakened

which causes blue shift of the emission peak of Eu

. With the increasing concentration of Dy

the energy transfer process from Dy

to Eu

is enhanced

and the emission intensity of Eu

increase. When the concentration of Dy

continued increase

the luminescence of Dy

decrease because of the effect of concentration quenching and the impaired energy transfer process from Dy

to Eu
