摘要

Nanocomposites of different concentrations of cadmium sulfide nanoparticles in a polyacrylamide shell were obtained as a result of the reaction of cadmium nitrate with acrylamide and a tiosulfiding agent (thiourea) in certain stoichiometric ratios followed by thermal polymerization of the reaction mixture. The samples were studied by the methods of elemental analysis, X-ray diffraction, scanning electron microscopy, and optical and luminescent spectroscopy. The sizes of sulfide nanoparticles as well as their distribution in the polymer were determined. It was shown that the absorption spectra have characteristic features of the spectra of composite systems with nanosized semiconductor crystals that manifested "defective" luminescence with a maximum in the 550-570 nm region.
