The optical properties of undoped zinc oxide layers prepared by isovalent substitution technique are discussed. The singularities observed in the reflection and luminescence spectra occurring at 3.2 and 3.265 eV are related to the energy distances between the conduction band and the valence subbands, the basic one and that split due to spin-orbit interaction. The emission bands at the energies less than 3.2 eV are formed by transitions of charge carriers with the participation of local centres.

Keywords: zinc oxide, luminescence and reflection spectra, band-to-band transition, local centres, optical phonons.
