Zinc oxide is a good material for application in nanoand optoelectronics due to its notable features, for example, large band gap. In this work ZnO films deposited by reactive magnetron sputtering at various pressure of residual gases and different temperatures of the substrate are investigated. The spectral dependences of ellipsometric parameters and of the films are determined by ellipsometry. The...
Synthesis conditions influence on structure of FexCoyOz - nanoparticle in SiO2 - sol-gel coating is discussed. The samples are synthesized by hybrid sol - gel method including following stages: TEOS hydrolysis, introduction into sol of Co(NO3)2 . 6H20 and Fe(NO3)3 . 9H20, deposition of film-forming sol by spin-coating on silica substrate, heat treatment at the temperature from 200 up to 900 °C. The...
Introduction of small amounts of dopant Fe cations intitania was mainly intended for improving the oxidativepower of the host TiO2 surface, by shifting the absorption edge of the material towards the blue side of the visible range. Apart from this, other possible applications of Fe-containing TiO2 materials have been foreseen in the field of diluted ferromagnetic semiconductors for spintronics. As...
