摘要

采用固相法合成了Eu

和Bi

共掺杂的LaMgB

红色荧光粉

在紫外或蓝光激发下

样品的红光强度随着Bi

的增加而增强。利用X射线衍射对样品的结构进行了分析

结果表明

掺入Bi

后

样品的结晶度更好。根据Judd-Ofelt理论计算

得到样品的内量子效率不随掺杂剂的改变而变化

约为43%。在394 nm激发下

和Bi

共掺杂样品的红色荧光强度较Eu

单掺杂样品中增强了50%。根据漫反射和变温光谱测量结果

分析指出Eu

红色荧光增强是由于Eu

的吸收增强。

Abstract

Red phosphors of Eu

and Bi

single- and double- doped LaMgB

have been synthesized by a solid-state reaction. The red emission intensities were enhanced with the increase of Bi

content. The crystal structures were analyzed using the X-ray diffraction. It indicated that the crystallization is better in the codoped samples than the Eu

monodoped sample. According to the results calculated by the Judd-Ofelt theory

the internal quantum efficiencies keep a constant value of about 43%. Moreover

red emission intensity increase 50% in the codoped sample comparison with the Eu

monodoped one under 394 nm excitation. It was confirmed that the enhanced red photoluminescence is due to the increase of Eu

absorption strengths.
