Electrical Transport of Mixed Phased Glassy Nanocomposites

Abstract

Ionic conductivity and conductivity relaxation of ZnO doped silver molybdate glass-nanocomposite systems have been studied. X-ray diffraction studies have been carried out to obtain the particle size and the distribution of ZnO, Ag₂MoO₄, Ag₂Mo₂O₇ and Ag₆Mo₁₀O₃₃ nanoparticles dispersed in glass-nanocomposites. A symmetric stretching of the Mo–O octahedral units has been found in the FTIR study. It has also been noted that as ZnO content increases, the bond strength of Mo–O becomes weaker. Ionic relaxation data of glass-nanocomposites have been analyzed in the framework of the electric modulus formalism. It has been observed that the electrical conductivity depends upon the ZnO content added to the system.
