Summary:Se1-xSx bulk glasses, within the composition range x = 0.1-0.5, were prepared from high purity constituent elements. The X-ray structure factors obtained from these glasses showed the presence of the first sharp diffraction peak (FSDP), which is the most universal signature of intermediate range order (IRO). The position and the full-width at half-maximum (FWHM) of the observed FSDP which relate, respectively, to the intercluster distance and the cluster size remained essentially the same. The intensity of this peak increased with the S content in the glasses. These results were interpreted by proposing that the IRO in this system is related to the formation of ring-like clusters. 41 refs.
