Investigation of scintillation properties of Hf-based oxide materials

The scintillation properties of Hf-based oxide materials are reviewed briefly. In particular, we focused on the undoped, Ti-doped, and rare-earth-doped HfO2, MHfO3 (M = Ca, Sr, and Ba), and RE 2Hf2O7 (RE = La, Gd, and Lu). The properties explained here are scintillation spectra, scintillation decay, and light yield estimated by the measurement of the pulse height distribution. Further, the synthesis methods of Hf-based oxide material single crystals and transparent ceramics are included in this review because the development of Hf-based oxide material scintillators is largely influenced by advances in the synthesis technology of single crystals and transparent ceramics.
