本文介绍了对Lu2SiO5：Ce(LSO：Ce)进行的实验结果。它寻找光产额、非均衡性和其他闪烁特性的潜在关联，例如本征能量分辨率与热释光特性。所分析的样品选自具有显著不同性质的不同晶体批次。将LSO：Ce单晶样品耦合到XP2020Q光电倍增管和大面积雪崩光电二极管上，在室温和液氮温度附近测量了14.7-1770keV的伽马射线能量函数。为了解释从光谱方法获得的实验结果，用热释光技术进一步研究了样品在250-600K温度范围内的性质，并报道了这两种实验数据之间的关系。
This work presents the results from experiments performed on Lu2SiO5:Ce (LSO:Ce). It looks for potential correlations of light yield nonproportionality and other scintillation properties such as intrinsic energy resolution with thermoluminescence properties. The analyzed samples were chosen from various crystal batches having significantly different properties. Single crystal LSO:Ce samples were coupled to an XP2020Q photomultiplier and to large area avalanche photodiodes and measured as a function of gamma-ray energy between 14.7 and 1770 keV at room temperature and also near liquid nitrogen temperature. To explain the experimental results obtained from spectrometric methods, the properties of the samples were further studied using thermoluminescence techniques within the temperature range from 250 K to 600 K. The relationships between data obtained from these two types of experiments are reported.
