| Abstract: | Rayleigh and Mandelstam–Brillouin light scattering has been investigated in chalcogenide glasses of the Ge–Sb–S system along the (Sb2S3)х(GeS2)100–х set (х = 0–50 mol %). Propagation velocity of the longitudinal hypersound wave, the high-frequency longitudinal elastic modulus, the extinction coeffi cient at the wavelength λ = 0.6328 microns, and the Landau–Placzek ratio are determined. The Landau–Placzek ratio for the glassy alloys of the Ge–Sb–S system depends strongly on the average coordination number and becomes maximal at Z = 2.67. |
