title: Coordination of graphene oxide with Fe3O4 nanoparticles and its enhanced optical limiting property.
abstract: A graphene oxide-Fe3O4 (GO-Fe3O4) hybrid material was prepared by a simple chemical precipitation method. The formation of this hybrid material was verified by Fourier transform infrared spectroscopy, high resolution transmission electron microscopy and X-ray powder diffraction. The optical limiting performance of this hybrid material was studied using the Z-scan measurement, which shows a much enhanced optical limiting performance compared with GO and is comparable with the benchmark material-C60. The mechanism responsible for this enhancement may be attributed to the enhanced nonlinear scattering effect introduced by the Fe3O4 nanoparticles.
