Structural properties of chalcogenide glasses As₂Se₃ doped with manganese

The paper presents the results of studying structural properties inherent to chalcogenide glasses doped with manganese. Investigations of the structure were carried out using Raman spectroscopy and X-ray diffraction. The function of radial distribution of atomic density and Raman spectra have been obtained and analyzed

Photoluminescence of As₂S₃ doped with Cr and Yb

The results of experimental researches of photoluminescence spectra in As₂S₃ glasses obtained by doping of Cr and Yb ions to As–S host matrix followed by Raman and calorimetric studies as well as low-temperature magnetization measurements have been given. Possible mechanisms of obtained effects are discussed
