摘要：

Gd2Hf2O7 and Lu2Hf2O7 single crystals doped with various rare-earth ions (Ce3+, Pr3+, and Tb3+) were prepared by the floating zone method to investigate their photoluminescence and scintillation properties. The Ce-doped samples show scintillation signals with a broad peak in the range of 400-600 nm, whereas the Tb-and Pr-doped samples show relatively strong emission characterized by a few sharp peaks in the range of 480-700 nm due to 4f-4f transitions of the dopant ions. The scintillation spectra of the Ce-doped Lu2Hf2O7 after annealing at various temperatures show significant changes in their shapes, suggesting changes in the valence of the Ce ions.
