Abstract

Roman scattering measurement of (1-x) GeS_2-xGa₂S₃ system glasses was conducted in order to understand the microstructural change caused by the addition of Ga₂S₃. According to the change of Raman spectra with the addition of Ga₂S₃, two main structural transformations were deduced: the gradual enhancement of ethane-like structural units S₃ Ge-Ga₂S₃(250 cm^-1) and S₃ Ga₂S₃ (270 cm^-1) and the appearance of charge imbalanced units [Ga₂S₂ (S_1/2)₄]^2- and [Ga(S_1/2)₄]^-. And this change of structural aspect seems to give us a clue to understanding the cause of the increased rare-earth solubility.
