In article are presebted the results of study the structural, optical, photoluminescent and photoelectric properties structure of the layer thin-film ZnO on the monocrystal LiNbO3 substrate. Presents the results of X-ray structural analysis of a zinc oxide thin film synthesized on a single-crystal lithium niobate substrate and on a KU-1 quartz substrate are presented. Are presented the results investigations of transmission spectra, reflection spectra and absorption spectra in the ultraviolet and visible spectral range. Are presented investigations spectral dependence of photoluminescence and the spectral dependence of the photoconductivity currents in the thin film structure of ZnO-LiNbO3 and the structure of ZnO-SiO2 in the ultraviolet and visible spectral range.
