Abstract

We study the optical limiting (OL) property of a newly emerged MXene material, niobium carbide (Nb2CTx) nanosheets, using nanosecond laser Z-scan measurement. The nanosheets exhibited excellent OL property, and the OL thresholds are estimated to be about 0.35 and 0.44  J  /  cm2 for 532 and 1064 nm, respectively. Compared with the traditional OL material, reduced graphene oxide, Nb2CTx nanosheets show a better OL property. The nonlinear scattering (NLS) measurements indicate that the excellent OL behavior of the nanosheets originates mainly from the strong NLS effect due to the good photothermal property of the material.
