Abstract: New glassy nanocomposites, yMoO 3 - (0.1 – y)V 2 O 5 – 0.9 (0.05ZnO - 0.95CuO) is found significant not only for surveying their microstructures using X-ray diffraction, FT-IR and SEM techniques, but also for setting out to explore their electrical conduction mechanism in terms of bi-polaronhopping process. Different nanophases such as Cu 4 O 3 , ZnO, Cu 3 Mo 2 O 9 etc. have been identified and the average size of estimated nanocrystallites is found to increase with MoO 3 content.As MoO 3 content is incorporated gradually, orthorhombic phases are found to be the major phases containing TMIs. Formation of more orthorhombic phases with higher MoO 3 incorporation may directly indicate the stable structure of the resultant glassy nanocomposites.Electrical conductivity of the present system has been analyzed using bi-polaron hopping process, which may take place among various localized states in the extended stable orthorhombic structures. Significant increase in density of states near Fermi level, N(E F) at higher temperature may directly indicate the expansion of the present glassy structure with more and more MoO 3 incorporation. All experimental data have been used to frame a schematic model to explore conduction mechanism inside the present glassy system. [ABSTRACT FROM AUTHOR]
