摘要

本文给出了BaF

晶体被辐照前后的自发光谱、透射光谱和光激发光谱的变化。结果表明，经

137

Cs和

Co的γ射线辐照后的BaF

晶体有较强的自发光，在310nm和650nm附近有两个峰。不同晶体的自发光谱不完全相同，同一块晶体的光谱形状不随受照剂量的大小而改变，但光的强度却与受照剂量有关；自发光随时间的衰减具有多种成分。辐照后BaF

晶体的透射率下降，恢复缓慢，但紫外光照射可以加速透射率的恢复。290nm的光能激发出BaF

的慢成分光，不同晶体的光激发发射光谱不完全相同，但辐照后无明显变化。

Abstract

We have studied the afterglow

transmission and light-excited fluorescence spectra of BaF

crystals before and after being irradiated. The results show that BaF

has strong afterglow near 310 nm and 650 nm after being irradiated with

137

Cs and

Co γ-rays. The transmission of BaF

crystals decreases after being irradiated

and its recovery is quite slow but becomes fast when BaF

is irradiated with ultraviolet. The light of 290 nm can excite the slow component of the fluorescence of BaF
