Abstract

Raman spectra of GeS₂-Ga₂S₃-CsCl pseudo-ternary glasses at room temperature in the air were probed systematically in the 150-500 cm^-1 region. Based on the evolution of Raman spectra and preparing procedure in pseudo-binary systems GeS₂-CsCl and Ga₂S₃-CsCl, the sole interaction of Ga₂S₃ and CsCl was identified and the formation of new units GaS_3/2Cl was verified in GeS₂-Ga₂S₃-CsCl glasses. That Cs⁺ ions in the form of Cl as the nearest coordination are homogeneously dispersed in the polymeric network was confirmed by the Raman spectra evolution of samples on two serials. Raman spectral evolution of two composition serials can be successfully interpreted by using a localized model considering the effect of Cs⁺ ions on the structural units GaS_3/2Cl and Ga₂S₄Cl₂.
