Abstract
Core-valence, self-trapped exciton and Ce3+-luminescences in pure and doped LiBaF3 crystals were determined on the basis of analysis of the time resolved emission and excitation spectra. It is shown that excitation of Ce-luminescence is caused both by carriers capture at or near activator ions and by energy transfer mechanisms. Parameters of the Ce3+ emission and n-gamma discrimination ability allow to use the LiBaF3(Ce) crystals as scintillators.
