摘要

采用高温烧结法制备了Lu2O3:Pr,Hf陶瓷，并对其热释光特性进行了研究。在x射线或深紫外光子刺激后，在110°C、220°C和310°C左右观察到强热释光带。发现最低温度峰值在最初几个小时内完全消退。然而，发光曲线的其他组成部分仅在黑暗中几个月后才显示出可测量的褪色。

Thermoluminescence characteristics of Lu2O3:Pr,Hf red emitting storage phosphor

Lu2O3:Pr,Hf ceramics were prepared by means of high temperature sintering and their thermoluminescent characteristics were investigated. After stimulation with X-rays or deep-UV photons strong thermoluminescence bands peaking at around 110°C, 220°C and 310°C were observed. The lowest temperature peak was found to fade completely within first few hours. However, the other components of the glow curve showed measureable fading only after a few months in dark.
