Abstract
- Nickel oxide nanoparticles have been synthesized via simple hydrothermal method. The structural, morphological, optical and magnetic properties of the as-synthesized products were examined by X-ray diffraction (XRD), scanning electron microscope, UV–Vis spectroscopy, photoluminescence (PL) and vibrating sample magnetometer (VSM). XRD patterns of pure cubic structured NiO nanoparticles were revealed with average grain size of 13 nm. The optical band gap was found to (3.69, 3.66 and 3.64 eV) decreases with increasing molar concentration of the precursor. PL spectra at room temperature showed a strong blue emission band and thereby confirm the above results. VSM results demonstrate that the NiO samples exhibit perfect room temperature ferromagnetism.
