摘要

利用 Czochralski 方法首次生长出了衰减时间较短的新型 YAG:Yb:Mg 和 YAG:Yb:Ca:Mg 晶体。研究了新型闪烁体的脉冲阴极发光光谱、光输出和衰减时间。发现 YAG:Yb:Mg 和 YAG:Yb:Ca:Mg 晶体的光输出分别为 460 和 770 光子/兆电子伏。研究表明，新晶体的衰减时间光谱由两个部分组成：YAG:Yb:Mg 衰减时间为 1.57/8.5 ns，YAG:Yb:Ca:Mg 衰减时间为 1.52/7.79 ns。

New Scintillation Crystals YAG:Yb3+:Mg2+ and YAG:Yb3+:Ca2+:Mg2+ with a Short Decay Time

New YAG:Yb:Mg and YAG:Yb:Ca:Mg crystals with a short decay time are grown for the first time using the Czochralski method. The pulsed cathodoluminescence spectra of the new scintillators, their light output, and decay time are studied. The light output of the YAG:Yb:Mg and YAG:Yb:Ca:Mg crystals are found to be 460 and 770 photons/MeV, respectively. It is shown that the decay time spectra of the new crystals are described by two components: 1.57/8.5 ns for YAG:Yb:Mg and 1.52/7.79 ns for YAG:Yb:Ca:Mg.
