使用顶晶溶液生长 (TSSG) 方法生长具有三斜结构的 La 替代 GPS，以减少铈引起的浓度猝灭。选择2.5%的低铈浓度和三斜晶种进行晶体生长。生长的La-GPS单晶的光产量是NaI:Tl的1.2倍。 662 keV 伽马射线的衰减时间和能量分辨率分别为 90 ns 和 7.1%。
La-substitute GPS with triclinic structure was grown using a top-seeded solution growth (TSSG) method to reduce concentration quenching by cerium. The low cerium concentration of 2.5% and triclinic crystal seed were chosen for crystal growth. The grown La-GPS single crystal showed light yield that was 1.2 times larger than NaI:Tl. Decay time and energy resolution for 662 keV gamma-rays were, respectively, 90 ns and 7.1%.
