Resumo

The atomic structure of the binary AsSe, ternary (AsSe)80Ag20, (AsSe)85I15 and quaternary (AsSe)65(AgI)35 glasses has been studied with the X-ray and neutron diffraction. The local order was also probed with the extended X-ray absorption fine structure spectroscopy at Ag, As and Se K-edges. All experimental data were modeled simultaneously by the reverse Monte Carlo technique. Analysis of the partial pair distribution functions and their characteristics enabled to retrace the structural changes from binary AsSe to pseudo-binary (AsSe)100� x(AgI)x system and to study the influence of Ag and I incorporation on the local structure. � 2007 Published by Elsevier B.V.
