The nature of intrinsic recombination emission in SrSO4 irradiated with ultraviolet photons

Abstract

The synthesized SrSO4 crystalline powders were irradiated at photon energies from 6 . 12 eV, in the temperature range from 15 . 300K. The investigationwas carried outbythe methodsof atomic absorp tion, 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.The synthesized SrSO4 crystalline powders were irradiated at photon energies from 6 . 12 eV, in the tem perature range from 15 . 300K.
