  • Intermediate range order in Se1−xSx bulk glasses
  • Published at:Materials Letters, Volume 35, Issues 5-6, June 1998, Pages 314-316
  • Se1−xSx bulk glasses, within the composition range 0.1≤x≤0.5, were prepared from high purity constituent elements. The X-ray structure factors obtained from these glasses show 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, remain essentially the same. The intensity of this peak increases with the amount of S content in the glasses. We interpret these results by proposing that the IRO in this system is related to the formation of ring-like clusters.
