This paper describes the first report of a Pr3+-doped transparent ceramic Lu 3Al5O12r; (Pr:LuAG) scintillator. Transparent ceramic Pr 0.25 mol% doped LuAG was developed by a sintering method, and achieved 70% transparency at wavelengths longer than 310 nm. The emission wavelength of the ceramic Pr:LuAG shifts to longer wavelengths than that of its single crystalline counterpart. The light yield was measured by irradiation of 137 Cs, and was almost half as that of the single crystalline counterpart. The energy resolution at 662 keV was 12% which was about three times as worse as that of the single crystalline one. The decay time showed a big difference with the single crystalline one because its slower component disappeared due to defects.
