Cerium-doped Gd3Al2Ga3O12 single crystals were grown by the Czochralski method with 1 at.% cerium. Absorption, luminescence and scintillation characteristics were investigated. The light yield and energy resolution were measured under 662 keV γ-ray excitation. The characteristic emission band of Ce3+ 5d-4f transition peaking around 525 nm was observed in the photoluminescence of Gd 3Al2Ga3O12:Ce. The light yield of 56,100 ph/MeV and energy resolution of 6.8% were obtained for a 5 × 5 × 1 mm3 Gd3Al2Ga3O 12:Ce sample. The light yield dependence on the sample height and on the shaping time was also studied and compared with Lu3Al 5O12:Ce crystal.
