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.
