Raman spectroscopy has been used to study the local structure in glass
y compositions of the ternary system As2S3-Sb2S3-Tl2S. The evolution o
f the positions and shapes of the bands observed is attributed to modi
fications in the environment of arsenic and antimony corresponding to
structural changes as the composition is varied. (C) 1997 Elsevier Sci
