Influence of Annealing Process on the Photostimulated Luminescence Properties of CsBr:Eu2+
Source abstract
Abstract
采用高温固相烧结法制备了CsBr:Eu 2+ 粉体, 系统研究了退火处理后粉体的光激励发光谱、吸收差谱和光激励发光衰减时间等, 发现退火处理能有效提高CsBr:Eu 2+ 粉体光激励发光强度, 缩短其发光衰减时间. 重点分析了退火气氛与光激励发光性能之间的关系, 实验结果表明, 退火气氛中的氧取代溴离子Br - 成为替位氧离子O s - , 而氢原子将进入间隙位成为间隙氢原子H i 0 . 替位氧离子O s - 以及H i 0 和H 2i 0 都是有效的电子俘获中心, 并且它们与空穴俘获中心的形成密切相关.
