Abstract

The aim of this work is to study the possibility to increase the radiation hardness of Cd0.9Zn0.1 Te crystal using laser radiation. Pulsed Nd:YAG laser for this aim was used. Estimation of the crystalline lattice defects before and after irradiation by γ-ray using photoluminescence method in the experiments was applied. Experimental results showed the increase of the radiation hardness of CdZnTe crystal after irradiation by laser at intensity 1.20–1.80 MW/cm2.

激光辐照提高CdZnTe的辐射硬度

本工作的目的是研究利用激光辐射提高Cd0.9Zn0.1 Te晶体辐射硬度的可能性。采用脉冲Nd:YAG激光瞄准。采用光致发光法对实验中γ射线辐照前后的晶格缺陷进行了估计。实验结果表明，激光辐照强度为1.20 ~ 1.80 MW/cm2后，CdZnTe晶体的辐射硬度有所提高。
