摘要

The nonlinear optical (NLO) and optical limiting properties of a graphene oxide hybrid material coordinated with Fe3O4 nanoparticles (GO-Fe3O4) were studied by using the Z-scan technique at 532 nm in the nanosecond and picosecond regimes. Results show that GO-Fe3O4 exhibits enhanced NLO and optical limiting properties in comparison with the pristine GO in the nanosecond regime. Compared with fullerene (C-60) in toluene at different concentrations, GO-Fe3O4 exhibits a weaker optical limiting effect than C-60 at high concentration, but shows a stronger optical limiting effect than C-60 at low concentration in the high input fluence region.
