Study of Some Physical Properties of Sb2o3:In2o3 Ceramic Nano Composites for Modern Application

Abstract

     Thin films from Sb₂O₃:In₂O₃were prepared with different weights and then the membranes were prepared using a drop casting method with a annealing temperature (250C). Some structural properties of Scanning Electron Microscope SEM, EDX. SEM images depict the surface morphology of Sb₂O₃ nanocomposite before and after addition In₂O₃, EDX know the chemical compounds in the sample .and Atomic Force Microscopic AFM indicated an increase in grain size of Sb₂o₃with increased with changing In₂o₃doping. Also, the optical properties studies included recording the permeability and absorbance of the prepared membranes and the wavelength range (110-300) nm, and it showed that the permeability of pure sb₂o₃ has a high amount in the visible area and it has little absorbency. The study also included the calculation of the absorption coefficient (α), and the gap energy of direct electronic transmissions. It was found that the energy gap decreases with increasing distortion of In₂O₃ from (3.806, 3.734, 3.634, 3. 384) ev doping ratios (1%, 2%,3%,4%) respectively.
