Abstract
The spectra and kinetics of pulsed cathodoluminescence buildup and decay in LiF-TiO2 and LiF-WO3.crystals have been studied in the temperature range of 20–300 K. It is found that all the LiF crystals doped with metal oxides (Fe, Ti, W) have a similar structure of the luminescence centers – oxygen centers excited by impurities in Fe2O3, WO3 and TiO2 complexes. In all types of the crystals, the processes of energy transfer to luminescence centers are similar (buildup stage).
