本文介绍了新型 Ce 掺杂、快速、高效的 Z 混合 Lux(RE3+)1−xAP:Ce 晶体的开发。这些晶体通过直拉法生长，对于 Y3+ 离子，x=0.1、0.2 和 0.3，对于 Gd3+ 离子，x=0.6 和 0.7 之间，获得了良好的结果。测得的 Lux(RE3+)1−xAP:Ce 晶体的相对光产额比 BGO 高 40–75%，并且与 YAP:Ce 晶体的光产额相当。在 662keV 处测得的能量分辨率范围超过 8-15.3% fwhm，接近使用 YAP:Ce 获得的能量分辨率。还进行了室温以上的热受激发光 (TSL) 测量：根据陷阱状态对闪烁效率的预期影响，发现了 TSL 强度和光产量之间的反相关性。
This paper presents the development of new Ce-doped, fast and high effective-Z mixed Lux(RE3+)1−xAP:Ce crystals. These crystals have been grown by the Czochralski method and good results have been obtained with x=0.1, 0.2 and 0.3 for Y3+ions and roughly between x=0.6 and 0.7 for Gd3+ions. Relative light yields measured for the Lux(RE3+)1−xAP:Ce crystals are 40–75% higher than for BGO and are comparable to the light yield of YAP:Ce crystal. Measured energy resolutions at 662keV range over 8–15.3% fwhm and are close to the energy resolution obtained with YAP:Ce. Thermally stimulated luminescence (TSL) measurements above room temperature have also been performed: in accordance with the expected effect of trap states on scintillation efficiency, an anticorrelation between TSL intensity and light yield is found.
