Abstract

The aim of this paper is to study the photoluminescence spectra and photoluminescence excitation spectra in LiF-Li2O, LiF-WO3 and LiF-TiO2 crystals at 20-300 K. It is shown that the luminescence centers in LiF-WO3 and LiF-TiO2 crystals are oxygen ions O2- disturbed by defects. Two absorption bands within 6-4.5 eV and two luminescence bands with maxima at 3.1 eV and 2.64 eV correspond to these centers. The absorption and emission spectra of the oxygen center (3.1 eV luminescence band) are close to those for the (O2--Va) center.
