PbF₂ crystal has favorable properties such as a high density and short radiation length, while the scintillation light output is too small to obtain a photo-absorption peak under gamma ray excitation. In this paper, we report scintillation response for 0.1 or 0.5-mol % Ce, Eu and Ho doped PbF₂ crystals grown by an annealing method under 5.5-MeV alpha ray excitation. Although Ce doped PbF₂ crystals did not show intense photo- and radio-luminescence, Eu and Ho doped ones showed several peaks excited under UV and 5.5-MeV alpha ray excitation, respectively. Additionally, full-absorption peaks in the pulse height spectra of 0.1-mol % Eu and Ho doped PbF₂ were ascribed to 5.5-MeV alpha-rays.
