Inverse opal photonic crystals films combine interesting structural and optical properties. In this work (IOFs), were fabricated with graphene oxide nano-sheets as external matrices through cross linking of poly (methyl methacrylate) templates. First mono-dispersed PMMA colloidal crystals templates were prepared. Then a solution of precursor containing graphene oxide nano-sheets was dropped on the surface of the PMMA templates and heated in the oven at 37 C for 24 h. These samples were immersed in toluene to completely remove the PMMA opal template. Finally thin films of GO photonic crystal with and inverse-opal structure were obtained. The resulting structures displayed strong photonic properties due to the high structural order that endow the films with photonic stop bands and structural colors, which are visible to the naked eye. These IOFs exhibited a rapid reversible changes in their structural colors and reflectance peaks like evidenced by optical analyses as a response to alcohol and organic solvent.

Keywords: Inverse opal, photonic crystals, templating, graphene oxide, PMMA nano-spheres.
