Abstract

New LuScSiO₅ crystals with intrinsic luminescence are grown by the Czochralski method. Pulsed cathodoluminescence spectra of new scintillators and their scintillation decay times are studied for the first time. Using 662-keV γ-rays from the ¹³⁷Cs source, amplitude distributions of the number of luminescence counts (so-called photopeaks) are measured for new crystals. It is shown that the light yield of LuScSiO₅ crystals is 13 500 photons/MeV.

新型 LuScSiO5 晶体的闪烁特性

摘要

具有本征发光的新 LuScSiO ₅晶体通过直拉法生长。首次研究了新型闪烁体的脉冲阴极发光光谱及其闪烁衰减时间。使用来自¹³⁷ Cs 源的662 keV γ 射线，测量新晶体的发光计数（所谓的光峰）数量的幅度分布。结果表明，LuScSiO ₅晶体的光产额为13 500 photons/MeV。
