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 Tg temperature, no meaningful evidence of local structural and dynamical modifications has been observed around molybdenum.

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 Tg temperature, no meaningful evidence of local structural and dynamical modifications has been observed around molybdenum.
