“…Chalcogenide glasses, especially those doped with certain elements (Ge, Cu, Ag, Sn, etc. ), show very significant and unique chemical and physical properties, primarily electrical and optical, which, even today, make these materials attractive for scientific research and different applications [1][2][3][4][5]. Opportunities for the application of Cu-doped chalcogenide glasses are wide-ranging due to the possibility of programmed variations of the important thermal, thermo-mechanical, optical, structural, and electronic properties of chalcogenide glasses, induced by Cu introduction [6][7][8][9][10][11].…”
