ZnO is a wide band gap semiconductor with a band gap of about 3.37 eV at room temperature having a large exciton binding energy of 60 meV that can effectively generate electron-hole pairs by ultraviolet irradiation. It has been taking the focus of researchers as perspective optoelectronic, photovoltaics and photocatalyst [1] nanostructured film material due to its enormous advantages such as high photosensitivity, high quantum efficiency, low cost, and non-toxicity. It is important that the effects of conditions of deposition, impurities and native defects on the structure, optical and electrical properties of doped ZnO-based materials is still poorly known [2]. In general, the contribution of various impurities and defects in ZnO, which generally control such properties, should be determined. ZnO-doped films with various concentrations of Mg, Co, Cd and Nd, La, Y were grown on Si and glass substrates by atmospheric pressure MOCVD as well as by radio frequency magnetron sputtering, respectively. In this work, we present the results of complex investigations for the influence of different type of impurities on the microstructure by XRD, transmittance, Raman scattering and photoluminescence. The results of photocatalysis activity of nanostructures ZnO films with various doping elements will be also presented and discussed.
