Synthesis and characterization of CoWO4 nanoparticles via chemical precipitation technique

This paper has for its content the synthesis and the findings of structural, surface morphological, optical and electrical studies of CoWO4 nanoparticles. Precipitation method was employed for the synthesis of CoWO4 nanoparticles. To determine the average grain size of CoWO4 nanoparticles the X-ray diffraction pattern was used. The presence of CoWO4 nanoparticles was confirmed by the FT-IR spectrum. The scanning electron microscopy analysis revealed the facts about the surface morphology of CoWO4 nanoparticles. The transmission electron microscopic analysis helped to measure the size of the particle formed. The absorption spectrum and photoluminescence spectrum made it possible to analyze the optical properties of CoWO4 nanoparticles. The contribution of this work is that the dielectric properties such as the dielectric constant, the dielectric loss, and the AC conductivity of the CoWO4 nanoparticles were studied at different frequencies and temperatures.
