2 inch size Ce:Gd3Al2Ga3O12 (Ce:GAGG) single crystals were grown by the Czochralski(Cz) method using [100] oriented seed. The crystals were up to 120mm in length and 50mm in diameter were achieved and had no cracks. Luminescence and scintillation properties were measured.In order to determine light yield,the energy spectra were collected under 662keV gamma-ray excitation (137Cs source) were detected by a with avalanche photodiode(APD) S8664-55(Hamamatsu). The light yield of Ce:GAGG sample was calibrated from 55Fe direct irradiation peak to APD. The light yield was around 46,000 photon/MeV. Energy resolution was 4.9%@662 keV for 5 x5x 1 mm sample. The theoretical density of Ce:GAGG is 6.63g/cm3.
