The synthesized SrSO4 crystalline powders were irradiated at photon energies from 6 o 12 eV, in the temperature range from 15 (Formula presented) 300 K. The investigation was carried out by the methods of atomic absorption, luminescence and vacuum ultraviolet spectroscopy. Intrinsic emissions were found at 3.7-3.8 eV, 4.2-4.6 eV and 4.9-5 eV, and long-wavelength recombination emissions at 2.6-2.7 eV and 2.9-3.0 eV.
