摘要

Yttrium aluminum garnet (YAG) doped with Ce was synthesized via the co-precipitation method withNH(4)HCO(3) as the precipitant. The spectroscopic properties and the effects of the Ce doping concentration and sintering atmosphere on the crystal phasewere investigated. The dosimeter of YAG:Ce phosphor material was prepared to study the radioluminescence (RL) characteristics of a clinical linear accelerator. A satisfying linear relationship between the radiation dose and RL signal was obtained, which provided a reference for the YAG:Ce phosphor material used in radiotherapy and real-time remote radiation detection.
