  • 本文用透射法EXAFS和IR,Raman光谱等手段研究了以P2O5,为基体的非晶态铜离子导体的微观结构,得出了非晶结构网络中存在PO43-,CuO46-,CuO3I5-,PO3I2-等四元骨架结构单元,Cu+在结构网络空隙中有两种不同的分布状况。并在此基础上对材料在50℃左右存在的二级相变及Cu+的其它传导性能进行了定性的描述。

     

    Microstructures of the noncrystalline copper ionic conductors with the network former of P2O5 were studied by means of transverse EXAFS, IR and Raman spectra. From the results, it is derived that in these noncrystalline network structure, there are skeleton structure elements such as PO43-, CuO4-6, CuO3I5-, PO312- etc., and there are two different distributions for Cu+ ions in voids of the network. The second-order phase transition of the materials at about 50℃ and conduction properties of Cu+ ions are discussed.
