Abstract
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.
