Abstract
Light yield and light loss coefficient of Lu3Al5O12:Ce (LuAG:Ce) and Lu3Al5O12:Pr (LuAG:Pr) single crystals grown by the Czochralski method were investigated under excitation with α- and γ-rays. Photoelectron yield and energy resolution were measured using the XP5200B photomultiplier. The dependence of photoelectron yield on sample height was measured under excitation with α- and γ-rays and the light loss coefficient was evaluated. It was found that the light loss coefficient of LuAG:Ce is smaller than that of LuAG:Pr. The ratio of photoelectron yield under excitation with α- and γ-rays (α/γ ratio) was also determined and discussed. © 2016 Elsevier B.V.
