The paper presents the results of the investigation of the frequency
dependence of the dielectric parameters of electroluminescent
polycrystalline structures based on zinc sulfide doped with
copper in the dark and under light excitation in the visible
wavelength range. A positive photodielectric effect has been
established, which is most pronounced in the low-frequency
range, due to the formation of a space charge in the bulk of the
semiconductor. The experimental results have been interpreted
within the framework of the electric modulus formalism.
Keywords: electric modulus, photodielectric effect, space charge, electroluminor
