Abstrakt:	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. [ABSTRACT FROM AUTHOR]
