Abstract
Spectra of optical density, luminescence, and Raman scattering of micro- and nanodendrites of crystal zinc and tin sulfides in silica nanoporous glass (NPG) with average pore size 25 nm are presented. Sulfide nanodendrites were synthesized by sulfurizing of zinc and tin nanodendrites, which were grown in NPG pores by electrolysis. It is shown that the luminescence of sulfide nanodendrites is caused by the defects of crystal lattice. The main bands of Raman spectrum of nanodendrites are caused by transverse and longitude vibration modes of hexagonal ZnS (wurtzite) and stretching modes of 2H polytype of SnS2 with hexagonal cell. The obtained results can be used for creating of chemical and biosensors, and also in photovoltaics and photocatalyze.
