Data from: Femtosecond laser-assisted synthesis of silver nanoparticles and reduced graphene oxide hybrid for optical limiting

Reduced graphene oxide (rGO) functionalized with silver nanoparticles (Ag
NPs) is prepared using femtosecond laser ablation in liquids method. By
ablating the mixed aqueous solutions of silver nitrate and graphene oxide
(GO) using femtosecond laser pulses, Ag ions and GO are simultaneously
reduced and well-dispersed Ag NPs supported on rGO are obtained. The
effect of laser power, irritation time, and Ag ion concentration on the
optical property and morphology of the products are systematically
studied. The nonlinear optical (NLO) responses of the functionalized
graphene are studied using nanosecond Z-scan technique. The rGO hybrid
shows an enhanced nonlinear absorption effect compared with GO and rGO,
and thus exhibits an excellent optical limiting (OL) property with very
low activating threshold, which is estimated to be about 0.38 J/cm2. The
enhanced NLA effect in rGO hybrids makes it possible to fabricate
solid-state optical limiter, improving the practicality of graphene
materials in OL area.
