Paper Abstract

We synthesize the Fe2O3 nanoparticles (NPs) by a co‐precipitation method and embed them into a polyvinyl alcohol (PVA) film to fabricate the filmy sample. Then we study the third-order nonlinear optical properties of Fe2O3 NPs in the form of Fe2O3-PVA film, adopting the fs I-scan technique. TPA β=3.44×10-5m/W and self-focusing γ=3.78×10-11m2 /W of Fe2O3 NPs are obtained at 800nm under 35fs pulse excitation. Both the nonlinear absorption and refraction are stronger than these reported previously, indicating this material is a good candidate for all-optical switching, photonic and optoelectronic applications in the future.
