Abstract
The effect on band gap (Eg) and crystal structure of ZnO modified by Al2O3, ZrO2, SiO2, CeO2, TiO2 and Y2O3 nanoparticles at concentrations less than 30 wt% has been investigated. Established that change of Eg reach to 0.03 eV and determined by charge of cations and their radius, as well as the concentration of the nanoparticles. Lattice parameters changes at modifying by nanoparticles with a smaller and larger radius of cations than the ion Zn2+. Influence of 100 keV protons irradiation result in blue shift in absorption edge of polycrystalline zinc oxide modified by Al2O3, ZrO2, SiO2, CeO2, TiO2 and Y2O3 nanoparticles.
