摘要：

Measurements of light yield, low temperature thermoluminescence, and scintillation time profiles, performed comparatively on "as grown" and thermally annealed LuAG:Pr samples, are reported. It is shown that traps play an efficient role in the scintillation of LuAG:Pr, being responsible for the yield decrease and introducing a long component to the time profiles. The trap concentrations in the annealed crystals are lower than in the non-annealed ones, which correlates with the yield enhancement. (C) 2013 Elsevier Ltd. All rights reserved.
