Synthesis of NiO nanoparticles by a simple chemical method

NiO nanoparticles with diameters in the range 15-30 nm have been synthesized using the surfactant P123 in a liquid medium. The particles were characterized by X-ray diffraction and transmission electron microscope. The particle exhibit photoluminescence in the UV range with maximum intensity at 315 nm. due to optical band gap of the material. DC electrical resistivity was found to have an activation energy 0.23 eV. These materials are expected to find applications as electrodes in lithium ion batteries as also in fabrication of solar cells.
