The Ca0.5% and Ce1%,3%,7%,10% co-doped Gd0.5Y0.5F3 single crystals were grown by the m-PD method. In the Ca0.5% and Ce3% co-doped sample, Ce3+-perturbed luminescence at 380 nm was observed with 32.4 ns photoluminescence decay time. The energy transfer in the sequence of the regular Ce3+- (Gd3+)n-the perturbed Ce3+ sites was evidenced through observation of decay times hortening of the regular Ce3+ and Gd3+ centers and the change between the Gd3+ and Ce3+-perturbed emission intensity. The gamma-ray excited scintillation response of the Ca0.5%,Ce7% co-doped Gd0.5Y0.5F3 sample was investigated.
