摘要
LuYAP:Ce晶体是YAP和LuAP的固溶体,具有衰减时间短,光产额高,密度高,有效原子序数大及不潮解等特性。随着镥组分含量的增加,晶体密度和有效原子序数随之增加,衰减时间更短。采用提拉法生长了φ35mm×100mm的高镥组分LuYAP:Ce闪烁晶体,晶体透明,无相分解现象。通过X线荧光光谱分析法(XRF)检测了晶体中的元素含量,测得Lu、Y摩尔比接近7∶3。另外还测试了该晶体退火处理前后的光输出变化,光输出性能提高了约16%。
LuYAP：Ce is mixed crystal of YAP：Ce and LuAP：Ce,possessing the features of short decay time,high light yield,high density and effective atomic number,no deliquescence.The shorter decay time,higher density and effective atomic number display with lutetium component increasing.The crystal boule with φ35mm×100mm has been succesfully grown by Czochralski method,which is transparent,no phase-decomposition.The element component was determined by XRF method.The Lu/Y ratio was close to 7∶3.The light output was also measured before and after crystal annealed.An increase of 16% was obtained.
