英文摘要	Four groups of Ge-Sb-Se chalcogenide glasses with compositions of GexSb10Se90-x (10 <= x <= 32.5), GexSb15Se85-x (5 <= x <= 27.5), GexSb20Se80-x (5 <= x <= 25), and Ge12.5SbxSe87.5-x (5 <= x <= 25) were prepared to systematically study their structural, thermal, and optical properties over a very wide compositional range. The structures, densities, glass transition temperatures, refractive indices, Vis-NIR and IR transmission spectra of the Ge-Sb-Se glasses show strikingly similar transitional features in the stoichiometric compositions. The transition behaviors of the structural, thermal, and optical properties of the Ge-Sb-Se glasses can be ascribed to the 'demixing' of the glassy network above the stoichiometric compositions.
