The electrical conductivity of WO3 nanoparticles synthesized with PVP by post-precipitation wet chemical technique


The synthesis of WO3 were using with polyvinyl pyrrolidone (PVP) by low cost wet chemical technique. The polyvinyl pyrrolidone (PVP) is used stabilizing and reducing agent. The effect of stabilizer concentration varies from in the range 0.025, 0.05 and 0.1M. The structural, AC and DC electrical properties of WO3 were successfully investigated. X-ray diffraction (XRD) studies show monoclinic phase structure of prepared WO3 nanoparticles. The DC conductivity was carried out in the temperature range from 303-403K which indicate semiconductor nature. The minimum activation energy was obtained in the higher temperature region. The frequency dependence of dielectric constant (ï¥â€™), dielectric loss (tan δ) and AC conductivity of WO3 nanoparticles of different PVP concentration were measured at room temperature. The AC conductivity was found to increases with PVP concentration. The DC conductivity was carried out in the temperature range from 303-403K which indicate semiconductor nature.
