摘要: 本文报道了用改进的坩埚下降技术生长PbWO4晶体经退火处理后,对X射线激发发射谱、透过谱以及抗辐照损伤能力的影响.指出PbWO4晶体在适合的富氧气氛环境和温度制度下经退火处理后,闪烁性能及抗辐照能力明显得到改善.

关键词: PbWO4晶体, 闪烁性能, 退火程序

Abstract: This paper described the influence of annealing process on X-ray irradiation excited emission spectra, transmission and radiation hardness of PWO crystals grown by a modified Bridgman method. The results show the scintillation properties and radiation hardness of PWO crystals annealed in the atmosphere with oxygen-rich and suitable temperatures are improved obviously.

Key words: lead tungstate crystal, scintillation properties, annealing procedure
