  4. Abstract:
  5. In this work, graphene oxide (GO) aqueous suspensions prepared by a chemical exfoliation method showed a fluorescence peak at ∼615 nm. Photoluminescence spectroscopy determined that functionalization of the GO sheets by 3-(2-Aminoethylamino) propyltrimethoxysilane molecules significantly quench the fluorescence property of the GO sheets. Fourier transform infrared spectroscopy confirmed proper functionalization of the GO sheets. Curcumin was applied as a fluorescent natural material with an emission peak at ∼550 nm wavelength for green fluorescent labeling of the functionalized-GO sheets. The curcumin-labeled functionalized-GO sheets showed an intense emission band fluorescent property with an emission peak at ∼540 nm. These results can provide applications of natural fluorescent materials (such as curcumin) in green fluorescent labeling of functionalized-GO sheets, which has attracted much attention for utilizing in upcoming bioapplications. © 2018 Elsevier B.V
