Infrared spectroscopic studies of ion-conducting silver phosphate glasses doped with zinc and cadmium halides

Abstract Silver phosphate glassed doped with different concentrations of zinc and cadmium halides have been prepared and characterized by using X-ray diffraction, elemental analyses, DSC studies, ion transport and infrared spectral studies. FTIR spectra of all the samples were done which indicate the presence of characteristic P  O  P linkages of linear polyphosphate chain and two non-bridging oxygen atoms bonded to phosphorus atoms (O  P  O units) in the phosphate tetrahedra. On the basis of IR studies, a plausible resonance chain structure for these glasses has been established and discussed.
