Luminescence and scintillation properties of Y 2 SiO 5 :Ce single crystalline film (YSO:Ce-LPE) grown by the liquid phase epitaxy technique are investigated and compared to the bulk Czochralski-grown YSO:Ce single crystal (YSO:Ce-SC). The light yield (LY) and energy resolution are measured using an R6231 photomultiplier under excitation with α and γ- rays. At 662 keV γ- rays, the LY value of 12,410 ph/MeV obtained for YSO:CeLPE is lower than that of 20,150 ph/MeV for YSO:CeSC whereas the comparable LY value and energy resolution are obtained under excitation with 5.5 MeV α- rays. The ratio of LY under excitation with α- and γ- rays (α/γ ratio) is determined. Dependence of LY on an amplifier shaping time (0.5–12 µs) is also measured.
