在华沙ITME,用Czochralski法生长了镨活化的LuAlO3(LuAP)晶体。在本次通信中,测量了辐射发光(RL),低温热释光(TL),室温余辉(AG),闪烁光产率(LY)和闪烁时间曲线(STP),在抛光2×2×10mm像素上进行了三种Pr浓度(0.003,0.04和0.08at)。%),被报告。比较两组样品:(i)“生长”和(ii)在H2atmosphere中退火。
Praseodymium activated LuAlO3(LuAP) crystals have been grown using the Czochralski method at ITME, Warsaw. In this communication the measurements of radioluminescence (RL), low temperature thermoluminescence (TL), room temperature afterglow (AG), scintillation light yields (LY), and scintillation time profiles (STP), performed on polished 2×2×10mm pixels with three Pr concentrations (0.003, 0.04, and 0.08at.%), are reported. Two sets of samples are compared: (i) “as grown”, and (ii) annealed in H2atmosphere.
