摘要

本文研究了用还原气氛法在箱式炉内制得的BaCl

:Eu

微晶及进一步处理后得到的BaCl

·2H

O:Eu

微晶的发光特性

包括发射光谱、激发光谱、热释光、光激励发光(存贮效应)及其温度依赖

就这些特性对BaCl

:Eu与BaCl

·2H

O:Eu进行了比较.根据发光光谱与激发光谱分析了它们具有良好光致发光特性的原因

讨论了这两种材料在热释光性能及光激励发光(存贮效应)上的明显不同

并对BaCl

·2H

O:Eu

中Eu

发光的增强提出了可能的解释.

Abstract

The luminescence characteristics of crystallites of BaCl

:Eu

which was prepared by the solid state reductive atmosphere in the box furnace

and BaCl

·2H

O:Eu

were studied.The comparison between BaCl

:Eu

and BaCl

·2H

O:Eu

on emission spectra

excitation spectra

photo-stimulated luminescence (PSL)

and thermoluminescence (TL) are reported.The excitation and emission spectra show that both BaCl

:Eu

and BaCl

·2H

O:Eu

can be excited by the ultraviolet light.At low concentration of Eu

both materials can be excited most efficiently by 254nm from a low-pressure mercury lamp. At high concentration of Eu

they can also be excited efficiently by 365nm from a high-pressure mercury lamp.
