Since the light output of Zr4+ co-doped Ce:Gd2SiO5 scintillator improved compared with the Ce:Gd2SiO5 one, the light output and other scintillation properties of M4+/Ce3+ co-doped Gd3Al2 Ga3O12 (GAGG), where M = Zr, Hf, were investigated. (Gd1-x, Ce0.01, Mx)3Ga3Al2O12 (M=Zr, Hf, x = 0.001 and 0.0002) crystals were grown by the micro-pulling down (μ-PD) method. We found these samples had longer decay time constants and the light outputs of these co-doped samples were degraded compared with that of the conventional Ce:GAGG.
