Facile Preparation of Novel Zinc Oxide Nano Sheets and Study of Its Optical Properties
Journal Title: Asian Journal of Nanoscience and Materials - Year 2019, Vol 2, Issue 1
Abstract
The zinc oxide nano sheets were prepared by zinc sulfate and sodium hydroxide via precipitated method and, then, calcinated at 300 oC. In order to have a reliable characterization of the synthesized ZnO nanosheets, FTIR, XRD, FESEM, XRF, TGA and Raman techniques were applied. The phase and purity of zinc oxide nanosheets were confirmed by XRD and XRF, respectively. FESEM results showed the morphology of zinc oxide and revealed that the size of the prepared powder is in the range of nanometer. TGA analysis revealed that there are two endothermic reactions which have occurred at 35-200oC and 300 - 400oC temperatures. Optical spectra indicated that the band gap of the prepared nanosheets transmitted a red shift.
