为了寻找核聚变诊断中下散射中子闪烁体的候选材料，研究了Ce 3+掺杂20 Al（PO 3）3- 80 LiF玻璃的闪烁性能。APLF_（80）+~ 3Ce在~（241）Am放射性同位素激发下的5.5MeV α粒子衰变常数为32.1ns。此外，实验证明，足够低的余辉衰减曲线和改善的光输出的APLF 80 + 3Ce。
Scintillation properties of Ce3+-doped 20Al(PO3)3-80LiF glasses were investigated in order to seek a candidate for down-scattered neutron scintillator in nuclear fusion diagnostics. The decay constant of APLF80 + 3Ce with 5.5 MeV alpha particles from 241Am radioisotope excitation was measured to be 32.1 ns. Moreover, sufficiently low afterglow decay profile and improved light output of APLF80 + 3Ce were experimentally demonstrated.
