Fabrication and Characterization of Tin Oxide Inverse Opal by Template Method

Abstract

In this study, Tin Oxide (SnO2) inverse opal was fabricated by infiltrating SnO2 sol-gel precursor solution into Poly Styrene (PS) spheres crystal template which was generated via evaporative deposition self-assembling, then was heat treating at 500°C for two hours in controlled atmosphere box furnaces. PS spheres crystal template was characterized by Scanning electron microscope and Ultraviolet-visible-near infrared absorption spectrometer. The SnO2 inverse opal was characterized by Scanning electron microscope, Energy Diffraction Spectrum, X Ray Diffraction. The large-area, highly ordered SnO2 inverse opal was achieved in this paper.
