用31 P魔角自旋（MAS）和自旋回波NMR研究了（Ag 2S）（PxS 5）1-x系统玻璃的形成和离子导电晶体及玻璃组成的局域结构。玻璃形成包括0.5≤x≤0.67的组成范围。31 P MAS和自旋回波NMR数据揭示了玻璃和它们的晶体对应物的局部结构的显著差异。这一结果加强了以前在相关的赝二元硫族化物系统中的发现
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
