Luminescence of LiF crystals doped with metal oxide impurities

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 O_2- oxygen centers perturbed by impurities and Fe₂O₃, WO₃ and TiO₂ included in the oxygen complexes.
