Effect of Ga on the structure of Ge–Se–Ga glasses from thermal analysis, Raman and XPS measurements

Temperature modulated differential scanning calorimetry (TMDSC), conventional DSC, X-ray photoelectron spectroscopy (XPS) and Raman scattering experiments have been carried out on stoichiometric (GeSe2)1 − y (Ga2Se3) y chalcogenide glasses where y = 0 to approximately 0.3. A structural model is proposed to explain the experimental results and hence the high Er solubility in Ge–Se–Ga glasses.
