“…In the current scenario, nanocomposite materials are generally low-cost and highperforming materials due to their unique grain sizes, microstructure, high surface area, physicochemical, electrical andmechanical properties [1]. Theses materials have wider range of applications in various fieldssuch as sensors, [2,3] electronic devices, [4] catalyst, [5] and energy as well as memory devices [6,7] etc.Some metal oxides (like MnO 2 , ZnO, RuO 2 , TiO 2 , WO 3 and SnO 2 ) are doped with conducting polymers to form nanocomposite materials [8].Among these all the metal oxides, ZnO nanoparticle is a nontoxic, low cost and excellent semiconductor nanomaterial with wide band gap of 3.37eV and large excitation binding energy of 60 meV. ZnO nanoparticlesare doped with different ions (such as Al, Ni, Cu, Mn, Co, Mg, etc.)…”
