摘要

通过熔融法以及热处理

制备了Ce

掺杂含LiLuF

纳米晶的透明氟氧微晶玻璃。XRD结果表明

玻璃中析出的晶相为LiLuF

其晶粒大小随热处理温度的升高和时间的延长而变大。在330 nm紫外光激发下

掺杂的氟氧玻璃和LiLuF

微晶玻璃的发射为一峰值波长为370 nm的宽带光谱。微晶玻璃的发光强度显著高于未经过热处理的基础玻璃

并且随着热处理温度的升高及时间的延长

微晶玻璃的发光逐渐增强。微晶玻璃的370 nm发射的荧光寿命均长于基础玻璃的。

Abstract

Transparent Ce

doped glass ceramics containing LiLuF

nanocrystals were prepared by melt-quenching method with subsequent heat treatment. XRD results show that the precipitated crystalline phase in the glass matrix is LiLuF

. Under 330 nm light excitation

doped oxyfluoride glass ceramics containing LiLuF

nanocrystals show more intense emission than the as-made glass

and the emission intensity increases with the increasing of heat treatment temperature and time. The lifetimes of 370 nm emission of Ce

doped oxyfluoride glass ceramics are longer than that of as-made glass.
