Zr-doped and Ti-doped Gd2Hf2O7 single crystals were synthesized by the optical floating zone technique to evaluate their scintillation properties. The synthesized single crystals show scintillation signals with a broad peak at 510 nm, and scintillation decay curves consist of two exponential functions with decay time constants on the nanosecond order. Both the Ti and Zr doping processes seem to enhance the scintillation properties of Gd2Hf2O7. As afterglow characteristics, all the Gd2Hf2O7 crystals show similar afterglow levels after X-ray irradiation for 2 ms.
