摘要

在980 nm激光激发下，Er

/Yb

共掺的发光材料既可以在可见光范围产生上转换发光，也可以在近红外波段产生下转换发光，二者存在竞争关系。本文利用熔融淬火法制备了一系列掺杂不同Er

/Yb

浓度的氟氧化物玻璃陶瓷，测量了样品在980 nm激光激发下的上转换及下转换发射光谱。研究发现，改变Er

的掺杂浓度可以调控上下转换的发光强度。在此基础上，提出了上下转换发光的能量传递模型。本文的研究结果有利于该类材料在不同领域中的应用。

Abstract

Oxyfluoride glass ceramics with different Er

/Yb

concentration were prepared by the melt-quenching method. The up- and down-conversion emissions were measured under 980 nm laser excitation. It is found that the intensities of up- and down-conversion emissions can be adjusted by changing the Er

doping concentration. The energy transfer model of up- and down-conversion emission is proposed

which clarifies the previous disagreements about up- and down-conversion energy transfer processes. The results will be used in controlling luminescent processes at different application fields.
