Raman spectroscopy and X-ray diffraction studies of (GeS₂)₁₀₀₋x(SbSI)x glasses and composites on their basis

摘要

The structure and structural changes under the isothermal annealing ofud (GeS₂)₁₀₀₋x(SbSI)x (0 ≤ x ≤ 90) glasses were investigated by Raman spectroscopy andud X-ray diffraction methods. The nanoheterogeneous nature of these glasses structure hasud been revealed. The matrix of (GeS₂)₁₀₀₋x(SbSI)x glasses is basically built just of binaryud GeS4, SbS3 and SbI3 structural groups and contains a small amount of molecularud fragments with homopolar Ge - Ge and S - S bonds. The phase structure arising in theud glass matrix at crystallization corresponds to the structure of crystalline SbSI.
