The aim of the project consisted in coordination and development of fundamental investigations and technology of obtaining of the nanostructured materials. On the basis of performed investigations the mechanisms of conductivity were ascertained in the nanocomposite films based on the ferroic crystals, incorporated into the polymer matrix. Using the gaseous-phase growth method in the atmosphere of air the nanostructures of zinc oxide of different types were obtained for the first time. The composites based on microcrystals of K2LaCl5:Се and LaCl3:Се incorporated into KCl and NaCl, respectively, were obtained. There was ascertained the influence of surface, crystalline field and size effects on the luminescent parameters of the metal-organic complexes, encapsulated into polymer nanoparticles. The complex of spectral-kinetic parameters of luminescence was obtained for a set of the organic and inorganic nanophosphors, activated by ions of rare-earth elements. Using the method of contact exchange the nanosized particle of silver were synthesized. The method of functionalization of surface of the metals, silicium using arendiazonim salts is developed. Argental polyanilin was tested as active layer of the amperometric bio-sensor and chemical sensor for detection of hydrogen peroxide. Using the thiols modification the monolayer coat of clusters of the precisious metals is obtained and the scale of surface coat is defined. The optimal regimes are proposed for the thermo-temporal treatment of the composites with the purpose of obtaining of the nanoparticles with optimal structure and size. The influence of doping with yttrium on the crystallographic, electric and magnetic characteristics of ZrNiSn compound was esteblished. The crystalline structure of the new superionic Ag3GeS3Br was refined and its parameters of electroconductivity and activation energy were defined.
