The short-range order around molybdenum has been investigated in AgI-doped silver molybdate glasses (AgI)(x)(Ag2MoO4)(1-x) (with x = 0.67 and 0.75) by Mo-K edge EXAFS measurements as a function of temperature. The difference from crystalline Ag2MoO4 is weak. A softening of the Mo-O nearest-neighbours bond has been detected, but the MoO4 units still exhibit high rigidity. Above the T-g temperature, no meaningful evidence of local structural and dynamical modifications has been observed around molybdenum. (C) 2007 Elsevier B.V. All rights reserved.

Abstract
The short-range order around molybdenum has been investigated in AgI-doped silver molybdate glasses (AgI)(x)(Ag2MoO4)(1-x) (with x = 0.67 and 0.75) by Mo-K edge EXAFS measurements as a function of temperature. The difference from crystalline Ag2MoO4 is weak. A softening of the Mo-O nearest-neighbours bond has been detected, but the MoO4 units still exhibit high rigidity. Above the T-g temperature, no meaningful evidence of local structural and dynamical modifications has been observed around molybdenum. (C) 2007 Elsevier B.V.
