Abstract
Stannic oxide nanostructured sheets (SnO2-NS) were synthesized via a simple sol–gel method. Stannous chloride (SnCl2) was used as a starting material and gelatin as a stabilizer. The structures of the prepared samples were characterized by X-ray diffraction (XRD) analysis and Raman spectroscopy. The results showed that the SnO2-NS were crystallized in tetragonal structure. Field emission electron microscopy (FESEM) observation showed that the SnO2-NS, with thickness of 175nm, were grown by SnO2 nano-grains (≈80±20) also, it was seen that the SnO2-NS are formed only in present of gelatin. The minimum wavelength of transmission window was obtained to be 344nm due to SnO2-NS optical band gap (Eg=3.6eV) from UV–vis spectrum.
