摘　　要：采用提拉法生长了φ80 mm×100 mm的掺Ce镥铝石榴石(LuAG∶Ce)晶体和掺Mg的LuAG∶Ce(LuAG∶Ce,Mg)晶体,并测试了晶体室温下的闪烁性能。实验结果表明,通过Mg离子掺杂,晶体光产额从15 000±1 500 photons/MeV提高到30 000±1 500 photons/MeV,衰减时间从120 ns加快到54 ns。The LuAG∶Ce and LuAG∶Ce,Mg single crystals with a size of φ80 mm×100 mm were grown by Czochralski method,and the scintillation properties of the crystal at room temperature were measured.The experimental results show that the light yield of the crystal is improved from 15 000±1 500 photons/MeV to 30 000±1 500 photons/MeV by Mg ion doping,and the decay time is accelerated from 120 ns to 54 ns.
