Рure and doped LiBaF3 crystals. Investigation radiative and non-radiative processes in pure and doped LiBaF3 crystals. Methods are luminescence spectorscopy with time resolution, optical spectroscopy, thermoluminescence method; station "SUPERLUMI", spectrophotometers Specord M-40, Specord M-82, luminescence setting CДЛ-2, thermoluminescence setting. Energy bands parameters of LiBaF3 crystals were determined. It was found dopants, which effectively influence on spectral-kinetic LiBaF3 crystals. It was cleared up processes, which control losses by energy transfer from lattice to luminescence centers. Formation processes of color centers and energy storage processes were investigated. The results confirm perspective creation of scintillation, dosimetric media on the base of LiBaF3 crystals. Fields of application are radiation physics, spectroscopy solid state, material science.
