Ce1%:(GdxY1-x)3Al5O12 (x=0, 0.2, 0.4, 0.6 and 0.8) crystals were grown by the μ-PD method. In the range of x=0∼0.4, the grown crystals showed single garnet phase, but x=0.6 and 0.8 crystals showed secondary perovskite phase. In these crystals, Ce3+ 4f-5d emission was observed within 500-530 nm wavelength. Emission peaks shifted to shorter wavelength and the decay times was delayed with increasing Gd concentration. The light yield of Ce:(Gd0.6Y0.4)3Al5O12sample was around 13,000 photon/MeV. Scintillation decay time was around 111 ns.
