| Abstract: | The fraction of 4-coordinated borons and motional narrowing of lithium ion foroxysulfide glasses in the Li2S-B2O3 (-LiBr) systems are measured by the 11B and 7Li NMRtechnique. The structrural modifications resulted from the modifier Li2S and dopant LiBrcomponents and their effects on ionic conduction are discussed. |
