STRUCTURAL AND OPTICAL PROPERTIES OF (ZnO/MgO) NANOCOMPOSITES

Different solvents such as ethanol, ethanol-water and water mediated zinc oxide/magnesium oxide (ZnO/MgO) nanocomposites have been successfully synthesized by the facile precipitation process. The structure, purity, crystallite size and the phase of the synthesized ZnO/MgO nanocomposites are confirmed by the powder XRD patterns. The functional groups of the samples are confirmed by the FTIR analysis. The optical properties of the prepared ZnO/MgO samples are characterized by the UV-visible absorption and the PL emission spectroscopies. The UV and PL studies are used to determine the band gap, impurity, material quality and defect levels in the metal oxide nanocomposites.
