Solvothermal synthesis, characterization and optical properties of ZnO, ZnO–MgO and ZnO–NiO, mixed oxide nanoparticles

ZnO–MgO and ZnO–NiO mixed oxides nanoparticles were produced from a solution containing Zinc acetate, Mg and Ni nitrate by Solvothermal method. The calcination process of the ZnO–MgO and ZnO–NiO composites nanoparticles brought forth polycrystalline two-phase ZnO–MgO and ZnO–NiO nanoparticles of 40–80 nm in diameters. ZnO, MgO and NiO were crystallized into würtzite and rock salt structures, respectively. The optical properties of ZnO–MgO and ZnO–NiO nanoparticles were obtained by solid state UV and solid state florescent. The XRD, SEM and Raman spectroscopies of these nanoparticles were analyzed.
