Abstract
The luminescence spectra and luminescence excitation spectra have been investigated in the spectral range of 6.5-4.4 eV. Pulsed cathodoluminescence of LiF-WO3 and LiF-TiO2 crystals has been studied in the temperature range of 20-300 K. All LiF crystals doped with metal oxides are found to have similar luminescent properties and identical structure of the luminescence centers. It is assumed that photon and electron bombardment induces excitation of different types of O2- oxygen centers perturbed by impurities and Fe2O3, WO3 and TiO2 included in the oxygen complexes.
