Abstract
Raman spectra of GeS2-Ga2S3-KCl pseudo-ternary system glasses at room temperature in the air were probed systematically in the region of 150-500 cm-1. Based on the results of Raman spectra and preparing procedure in pseudo-binary systems GeS2-KCl and Ga2S3-KCl, the sole interaction of Ga2S3 and KCl was identified and new units GaS3/2Cl were produced in GeS2-Ga2S3-KCl glasses. That K+ ions in the form of Cl as the nearest coordination were homogeneously dispersed in the polymeric network was confirmed by the Raman spectra evolution of samples on the serials I and III. Raman spectral evolution of three composition serials can be successfully interpreted using a localized model considering the effect of K+ ions on the structural units GaS3/2Cl and Ga2S4Cl2.
