Opis:: A development of high-performance materials for electronics, optics, ceramics fabrication is restrained by traditional modes of their production. Basic technologies for materials include high-temperature physical and chemical processes and require special conditions to attain desired properties of final products. Advanced preparation methods for materials with new features are feasible on the basis of colloid-chemical processes and nanochemistry. In this respect the sol-to-gel transformation followed by solidification and chemical modification are of great interest to attain a variety of different functional properties of materials.

Opis:: Optically homogeneous double-coated of GeO2 -SiO2 films, sodoped by ions of silver and cerium were fabricated with use sol-gel of a method, using tetraethylorthogermanate (TEOG) and tetraethylorthosilicate (TEOS) as precursors for germania and silica, respectively. According to data IR-spectroscopy of a coat are glassy. Refractive indices for the materials were obtained the following: GeO2, n = 1.687 at thickness d = 530.5 nm and SiO2, n = 1.512 at d = 998.2 nm. They demonstrate good adhesion to the glass, germanium, silica and metal substrates. Introduction of Re-earth ions m allows to control refractive index within the limits of from 1,2 up to 1,6, that is important for deriving the multilayer antirefractive coats for the infra-red optics. Introduction silver nanoparticles allow using the yielded coats for magnification of efficiency of solar cells.

Opis:: Theeffect of freon heat treatment on optical properties of Er-doped silica glasses obtained by the sol-gel method was investigated. It was found that fluorine ions in the process of hydrolysis replace hydroxyl ions in the host and form the complexes with Er$\text{}^{3+}$ ions. It leads to a significant improvement of optical properties of Er doped silica glass.

Opis:: 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.
