Using the methods of vacuum ultraviolet spectroscopy and thermally stimulated luminescence, the nature of intrinsic and impurity luminescence and the formation of electron-hole trap centers are studied. LiKSO₄-Cu crystal were excited by photons of 4–12 eV and X-rays in the temperature range 15–300 K. The energy transfer by intrinsic electronic excitations to impurity Cu⁺ luminescence centers was demonstrated. The nature of radiation-induced emissions was studied at the temperatures of 15–80 K. The band gap of the LiKSO₄ crystal (about 5.64 eV) was estimated on the basis of the efficiency of energy transfer by electron-hole pairs to luminescent impurity centers.
