Abstract
- Glass formation and the local structure of ionically conductive crystalline and glassy compositions in the (Ag 2 S)(P x S 5 ) 1-x system have been investigated by 31 P magic-angle spinning (MAS) and spin-echo NMR. Glass formation encompasses the compositional range 0.5≤x≤0.67. 31 P MAS and spin-echo NMR data reveal striking differences in the local structures of the glasses and their crystalline counterparts. This result reinforces previous findings in related pseudobinary chalcogenide systems
