摘要：
We synthesized Pr6O11-MgO nanocomposites through sol-gel route using praseodymium acetate and magnesium acetate tetrahydrate. The grain size and the morphology of the synthesized nanocomposite were characterized using XRD and HRSEM. The elemental compositions of the synthesized samples were analyzed using EDAX spectra. The dielectric constant, tangent loss and AC conductivity of the synthesized samples were studied in the frequency range of 100 Hz-5 MHz at different temperatures (303-573 K) using impedance analyzer. The activation energy was calculated using Arrhenius plot. The results are discussed in this paper.
