The Effect of Annealing Temperature on the Structural Properties and Color Properties of Tin Oxide Thin Films by the Sol-Gel Method

Tin oxide thin films were produced by the (sol-gel) method, coated on glass substrates using the spin coating process, and plasticized at (200℃, 300℃, 400 ℃, 500 ℃). The required analyses, including UV-visible spectroscopy, AFM, and XRD, were carried out. In order to research the produced films' optical, structural, and color characteristics. All of the produced films possessed a tetrahedral crystalline structure, according to X-ray diffraction data. Studies using AFM technology showed that when the annealing temperature rises, transmittance falls and the rate of surface roughness increases. In this study, the CIE 1931 method was used to examine the color coordinates of tin oxide films. Three parameters related to color were measured: brightness, dominating wavelength, and purity.
