Self-Assembled ZnO Nanostructure by One Step Emulsion Combustion Synthesis 2020-28-0510

Self- assembled ZnO nanostructures were synthesized by a simple, rapid and cost- effective emulsion combustion method. The synthesized ZnO nanostructures have a hexagonal wurtzite structure. TEM micrographs of the sample consisted of looped chains that were <1 μm in length and consisted of 30-120 isometric 13-16 nm sized nanoparticles. The assembling of nanoparticles transforms from branched chain to linear network by increasing the molar concentration of oleic acid from 0.5 to 1.5. The linear network was <700 nm in length and width varies from 15-35 nm respectively. The oleic acid bonding with ZnO was confirmed by Fourier transform infrared spectroscopy. The optical band gap (Eg) of 3.34, 3.38 and 3.43 eV based on the absorption edge 371, 367 and 361 nm respectively. Magnetization study reveals that the ZnO sample exhibits diamagnetic behavior.
