Rezumat

In this paper we focus on structural properties of As2S3–Ag glasses in phase separation region (Ag content: 0, 5, 7 at. %) using XRD technique and Raman spectroscopy and report on some application of studied glasses. X-ray diffraction experiments confirm amorphous structure of glasses. Pair distribution functions have been obtained and analyzed, and they have testified about changes in the radius of the first coordination sphere after introduction of silver into As2S3. The changes of the structure can be observed from obtained Raman spectra of doped As2S3: Ag. Compositional changes in studied chalcogenide glasses were observed in the evolution of the detected Raman bands. The main effect that is observed at introduction of silver (5, 7 at. %) into nanostructured As2S3 glass is the change of the relative concentration of the main and non-stoichiometric molecular structural units. As2S3–Ag glasses are promising for application in the photonics and optical data storages. Surface relief holographic diffraction gratings were directly recorded using composite As2S3: Ag/Se nano-multilayered structures. Diffraction efficiency values in transmission of recorded gratings is ~22%.
