Abstract

Atomic structures of (Agl)x(AgPO3O3)1−x glasses for x=0.0, 0.1, 0.2, 0.3 and 0.5 have been investigated by X-ray diffraction. Coordination numbers and atomic distances in the near-neighbour region were determined by the least-squares variational method. The coordination numbers of P-O, P-P and O-O pairs are unchanged with x, which suggests no modification of the connectivity of the PO4 tetrahedral chains by doping with Agl. The coordination number of I around Ag+ linearly increases from 0 to 1.9 ± 0.2 with increase in x, while the coordination number of O2− around Ag+ linearly decreases from 5.1±0.2 to 2.5±0.2. This also suggests that the Agl gets into the PO4 chains while keeping the local environment of the Agi itself.
