Abstract: (1868 Views)
In this research, SnO2 Thin films were prepared by sol-gel dip-coating method on glass substrates. Then, in order to improvment of structural properties, the samples were annealed at three temperatures of 4000C, 4500C and 5000C. Structural, morphological and optical properties of the films were studied using XRD measurement, UV-Vis spectroscopy and FESEM, images. X-ray diffraction patterns showed an increase in the crystalline quality of the films as increases annealing temperature. The optical properties of the films showed all samples are transparent in the measured wavelength region (300-1100 nm). The optical study showed that the band gap of the annealed films increases as annealing temperature increases.
