Luminescent properties of barium fluorobromide crystals irradiated with xenon ions with energy E=229 MeV up to fluences (1 × 10 10 - 1 × 10 12 ) ion/cm 2 are investigated in this work. The photoluminescence spectra show the presence of an uncontrolled impurity, which is involved in the mechanisms of defect formation. Raman spectra from the surface of BaFBr single crystals were used to determine the lattice vibration frequencies as a function of the fluence. A decrease in Raman spectra intensity is traced as the fluence increases at frequencies belonging to fluorine ions.
