Preparation and Characterization of MgO Nanoparticles by Sol–Gel Method

Liquid phase method (sol–gel method) was employed to synthesize MgO nanparticles. The particles were subjected to structural, morphological and optical property studies. X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform Infrared Spectroscopy (FT-IR), UV-Vis Spectrophotometer were employed to characterize the given sample. The X-ray pattern obtained had no impurity peak, revealing high purity of the sample. The particle size and morphology were investigated by SEM. EDS and FT-IR studies were done for knowing the composition and surface passivation respectively of the prepared sample. The estimation of the band-gap was carried out by UV-vis absorption spectra.
