极端使役环境探测用Yb:Lu2O3超快闪烁晶体生长及性能研究
Growth and Characterization of Yb:Lu2O3 Ultrafast Scintillation Crystal for Extreme Service Environment Detection
摘要
Abstract
Yb3+-doped Lu2O3 crystal has emerged as an ideal material for ultrafast scintillation detectors in extreme service environments owing to its advantages of high temperature resistance,high density,and sub-nanosecond decay characteristics.This work reports on the study of the relevant performance of ultrafast scintil-lation Yb:Lu2O3 crystal grown by the temperature gradient technique.Thermogravimetric-differential scanning calorimetry,thermomechanical analysis and compressive strength tests demonstrated that Lu2O3 possessed excel-lent thermal stability and compressive strength.Irradiation with a 137Cs γ-ray source revealed a decay time of 1.5 ns and an absolute light yield of 56 photons/MeV.This study marks the first experimental measurement of the absolute light yield of Yb:Lu2O3 ultrafast scintillation crystals.This finding demonstrates the significant potential of Yb:Lu2O3 crystals as promising candidate materials for high-energy physics experiments and nuclear medical imaging.Its high radiation detection efficiency and excellent operational stability under high-tempera-ture and high-pressure conditions offer a promising strategy for optimizing the performance of next-generation scintillator devices.关键词
