摘要

Properties of praseodymium and cerium doped Lutetium Aluminum Garnet (LuAG) were compared with cerium doped Lutetium Oxyorthosilicate (LSO) and Lanthanum Bromide (LaBr3). Light yield, its non-proportionality relative to 662 keV γ-rays and the dependence of the energy resolution on energy of the detected γ-rays were measured. LuAG:Pr turned out to have good proportionality, with deviation from unity around 10% at 16.6 keV and 3% at 59.5 keV. This, together with relatively high light yield of 5600 phe/MeV results in a very good energy resolution of LuAG:Pr of 5.1% measured with 662 keV γ-rays. Coincidence time resolution was measured to be 308 ps, significantly larger than that of LSO:Ce - 166 ps. This can be explained by smaller light yield of LuAG:Pr and the fact that only around 25% of its scintillation is emitted in short decay time modes of 17.6 ns and 52 ns, while the rest is decaying with long time modes of 1.4 μs and 9 μs.
