In this report, the Ce: (Lu,Gd)3(Ga,Al)5O 12 single crystal were grown by the micro-pulling down (m-PD) method. Luminescence and scintillation properties were measured. The substitution at the Al3+ sites by Ga3+ and at the Lu3+ sites by Gd3+ in garnet structure has been studied. In these crystals, Ce3+ 4f-5d emission is observed with 500-530nm wavelength. Emission peak shifts to shorter wavelength and the decay accelerates with increasing Ga concentration. In the case of Ce: Lu2Gd1(Ga,Al) 5O12 series, Ce: Lu2Gd1Ga 3Al2O12 shows highest emission intensity. The light yield of Ce: Lu2Gd1Ga3Al 2O12 sample with 3mmφx1mm size was around 30,000photon/MeV using calibration from 55Fe direct irradiation peak to APD. Scintillation decay time was around 50ns. Density is theoretically 7.1g/cm3.
