The work presents the results of the study of the luminescence of uranium doped LiF crystals. Introduction of the dopant (U) and the co-dopant (OH) shows the occurrence of additional absorption in the range of 260-320 nm. The IR spectrum in crystals containing OH has distinguished characteristic absorption bands at 3725 cm-1. In crystals doped with (U), the bands 3550-3580 cm-1 are observed, which are responsible for OH ions. The doped crystals with co-dopant contain an additional band at 3342 cm-1. The luminescence is observed in the 470-520 nm spectral range excited by ionizing and UV radiation.
