Abstract. The structure and structural changes under the isothermal annealing of (GeS2)100-x (SbSI)x (0 〈 x 〈 90) glasses were investigated by Raman spectroscopy and X-ray diffraction methods. The nanoheterogeneous nature of these glasses structure has been revealed. The matrix of (GeS2)100-x (SbSI)x glasses is basically built just of binary GeS4 , SbS3 and SbI3 structural groups and contains a small amount of molecular fragments with homopolar Ge - Ge and S - S bonds. The phase structure arising in the glass matrix at crystallization corresponds to the structure of crystalline SbSI.
Keywords: chalcogenide glasses, Raman spectra, local structure, ferroelectric, nanocomposities.
