【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．更多还原

【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.更多还原
