Microstructural analysis of Ga2S3–2MCl (M=K,Rb,Cs) glasses using Raman scattering

Raman scattering spectra of Ga2S3–2MCl (M=K,Rb,Cs) glasses have been conducted at room temperature. Based on the analysis of the local co-ordination surroundings of Cs+ ions, the similarities and differences of Raman spectra for the glass Ga2S3–2CsCl and the bridged molecular GaCl3 were explained su...

Summary:Raman scattering spectra of Ga2S3–2MCl (M=K,Rb,Cs) glasses have been conducted at room temperature. Based on the analysis of the local co-ordination surroundings of Cs+ ions, the similarities and differences of Raman spectra for the glass Ga2S3–2CsCl and the bridged molecular GaCl3 were explained successfully. Through considering the effect of M+ ions on mixed anion units [GaS4−xClx] and bridged units [Ga2S6−xClx] and the corresponding microstructural model, the Raman spectral evolution of the Ga2S3–2MCl (M=K,Rb,Cs) glasses was reasonably elucidated.
