摘要：
We used gamma spectroscopy to study scintillation properties of the Pr3+-doped lutetium aluminium garnet material (LuAG:Pr). Characteristics of LuAG: Pr optical ceramic samples (0.5-5 mol % Pr3+ content) are compared with those of LuAG: Pr single crystal. N-phels photoelectron yield of Pr3+-doped optical ceramic samples reaches up to 30-40 % of that of LuAG: Pr crystal, while their energy resolution values are closer. Non-proportionality effect in optical ceramic samples is noticeably smaller with respect to single crystal below 500 keV.
