Abstract
The spectra of optical density, luminescence, and Raman scattering of crystalline micro- and nanodendrites of zinc and tin sulfides in silicate nanoporous glass (NPG) with an average pore size of 25 nm have been presented. Sulfide nanodendrites have been synthesized by sulfiding zinc and tin nanodendrites grown in the pores of the NPG by electrolysis. It has been shown that the luminescence of nanodendrites is caused by defects in the crystal lattice. The main bands of the Raman spectrum of nanodendrites are related to transverse and longitudinal vibrational modes of hexagonal ZnS (wurtzite) and stretching modes of the 2H polytype of SnS2 with a hexagonal elementary cell. The obtained results can be used in the creation of chemical and biological sensors, as well as in photovoltaics and photocatalysis.
