Abstract: Results of determination of efficiency of use of vacuum deposition and sol-gel synthesis of study for formation of nanocomposite coatings of ZnO$_{\text{x}}$ : MgO with band gap width greater than 5 eV and with high sensitivity to UV and visible radiation are presented. It has been shown that spectral sensitivity of heterostructure with band gap width ZnO$_{\text{x}}$ : Mg about 6.2 eV to UV radiation (278 nm) was from 0.3 A/W to 3.23 A/W at shift from 10 V to 14 V respectively.

Keywords: ZnO : MgO films, sol-gel method, electron-beam dispersion, band gap, volt-ampere characteristics, spectral sensitivity.
