Electric conductivity analysis and dielectric relaxation behavior of the hybrid polyvanadate (H3N(CH2)3NH3)[V4O10]

Layered hybrid compound (H3N(CH2)(3)NH3)[V4O10] has been synthesized via hydrothermal method. Techniques X-ray powder diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, and impedance spectroscopy have been used to characterize the hybrid material. Electrical and dielectric properties dependence on both temperature and frequency of the compound have been reported. The direct current conductivity process is thermally activated and it is found to be 12.67 x 10(-4) Omega(-1) m(-1) at 523 K. The spectra follow the Arrhenius law with two activation energy 0.25 eV for T < 455 K and 0.5 eV for T > 455 K. (C) 2013 Elsevier Ltd. All rights reserved.
