抄録
Quasielastic light scattering (QELS) due to hopping of Ag+ ions was studied on superionic glasses (AgI)x(Ag2OMoO3)1-x (x=0.60,0.70,0.75). The temperature dependence of the QELS intensity at a fixed frequency as well as the integrated QELS intensity were measured. The activation energy for ionic hopping did not depend on glass composition, and the value (0.1 eV) was close to that determined in -AgI. From these results, it was concluded that the local hopping of Ag+ ions in the region like -AgI contributes to QELS. It was found from the temperature dependence of the QELS intensity that the concentration of hopping ions increased with increasing temperature above 220 K. The increase in hopping-ion concentration may be related to a dc conduction process.
