Abstract

The spectra of the optical density and luminescence and dielectric spectra of crystalline nanoparticles (NPs), as well as micro- and nanodendrites of zinc and tin oxides in silicate nanoporous glass (NPG) with the average pore size of 25 nm, are presented. Oxide nanoparticles were synthesized in the bulk of nanoporous glass by the method of thermodissociation of zinc and tin salts. Oxide nanodendrites were synthesized by the oxidation of zinc and tin nanodendrites which were grown in glass pores via the method of electrolysis. It is demonstrated that the luminescence of nanoparticles and nanodendrites of Zn and Sn is caused by defects in the crystal structure. The optical and dielectric properties of the nanocomposites with nanoparticles and nanodendrites are compared. The obtained results can be used to create chemical and biological sensors, as well as in photocatalysis.
