STRUCTURAL PROPERTIES OF CHALCOGENIDE GLASSES As2S3 DOPED WITH SILVER

Investigation results on the effect of silver doping on the structural properties of chalcogenide glasses As2S3 have been presented. The study of the structure has been performed using the method of X-ray diffraction and Raman spectroscopy. The functions of radial distribution of atomic density and Raman spectra have been obtained and analyzed. Using radial distribution functions, one can conclude about certain increase of the first coordination sphere radius after introduction of silver into As2S3. Raman spectra show that the main effect observed after introduction of silver into As2S3 glass matrix is the change of the relative concentration of the main and non-stoichiometric structural units typical for As2S3 glasses.

Keywords: chalcogenide glass, radial distribution function of the atomic density, Raman spectra.
