Abstract

•The La-GPS with both low cerium concentration and the triclinic structure was grown using the TSSG method.•The grown La-GPS single crystal showed light yield that was 1.2 times larger than NaI:Tl.•Self-absorption of emission light was reduced by the reduction of cerium concentration.

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%.
