Abstract

The nature of intrinsic luminescence and electron-hole trapping centers in LiKSO 4 , LiNaSO 4 and Li 2 SO 4
under excitation by photons with energies 4 ÷ 12.4 eV at temperatures 15 ÷ 300 K are investigated using vacuum
ultraviolet and thermo-activated spectroscopy methods. The minimum energy of lithium-containing sulfates of mixed alkali metals is estimated creating intrinsic luminescence and electron-hole trapping centers. Based on the measurement of the excitation spectra, electronic transitions from the valence band to the conduction band for LiKSO 4 , LiNaSO 4 , and Li 2 SO 4 were identified.
