The Effect of Annealing Temperature on the Band Gap of ZnO Nano Materials

Abstract:

Zinc oxide nanostructures were prepared by sol-gel method without using any chelating agents. The structural and optical properties of the nanostructures were studied. The precursors were annealed at 400 °C and 800 °C for 24 hours and characterized using X-Ray diffraction (XRD) and Field Emission Scanning Electron Microscopy (FESEM). The band gap energies were analyzed by using a UV-Vis spectrophotometer. Based on the XRD results, all materials were single phase with the hexagonal structure without any impurities presents. Based on the FESEM results, it was found that the morphology for the materials annealed at 400 °C has nanorod shape while for the materials annealed at 800 °C, they have spherical shape. It was found that the band gap energies of the ZnO nanomaterials were dependent on the morphology of the nanostructures.
