Influence of synthesis conditions on the properties of FeXCoYOZ - nanoparticles in SiO2Sol-gel film

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 Synthesis conditions influence on a specific structural property of sol gel films is investigated by AFM.
