title: Conductivity relaxation in lodomolybdate glass-nanocomposites embedded with znO nanoparticles and alpha-AgI nanocrystals.
abstract: We have reported the conductivity relaxation of the 0.70AgI-0.15Ag20-0.15(xZnO-(1-x)MoO3), glass-nanocomposites embedded with ZnO nanoparticles and alpha-Agl nanocrystals. Formation of ZnO nanoparticles and alpha-AgI nanocrystals was confirmed from field emission scanning electron microscopy (FE-SEM) and high-resolution transmission electron microscopy (HR-TEM). It is observed that the conductivity relaxation process depends upon the size of the ZnO nanoparticles embedded in the host glass matrix. The variation of conductivity relaxation time and stretched exponent is correlated with their structure. The scaling of the modulus spectra reveals that the relaxation dynamics of Ag+ ions is independent of temperature but depends on composition.
