Absorption, emission, excitation and thermoluminescence were investigated for pure, Eu- and Ce-doped LiBaF{sub 3} crystals, both as grown and irradiated. It is shown that the purity of initial crystal is a prerequisite to reduce the afterglow and decrease the radiation damage level. Doping by Ce or Eu ions is a way to vary the spectral and kinetic characteristic. The exciton luminescence and blue afterglow are suppressed in Eu- or Ce-doped crystals. Radiation induced absorption spectrum is complicated and includes more than six overlapped bands. Emission of these color centers appears in the luminescence spectrum.
