Abstract
Comparative measurements of thermoluminescence and scintillation light outputs of gamma-ray irradiated Ce:LuAlO3 (LuAP) and Ce:YAlO3 (YAP) r eveal that electron trapping significantly depresses transfer efficien cy in these scintillator materials, but fails to explain fully either their performance differential or their departures from ideal efficien cy. In the limit of short radiation times, the ratio of integrated the rmoluminescence light output to integrated scintillation light output is 0.14 in LuAP and 0.02 in YAP.
