摘要：

Results of neutron diffraction, inelastic neutron scattering and Raman scattering measurements are presented for Li2SiS3 and compared with similar data for another fast-ion conducting glass, Ag4Ge3Se9. The structures are different in some respects, with the Li+ ions in fourfold-coordinated sites in Li2SiS3 compared with Ag+ ions occupying threefold-coordinated Sites in Ag4Ge3Se9. However, the effect of the fast-ion modifying component appears to be similar in the two systems, leading to a decrease in the number of edge-shared tetrahedra and breaking the connectivity of the network, thus facilitating the high mobility
