摘要：

We investigated the nonlinear response of Co3O4 nanoparticles (NPs) dissolved in liquid n-heptane. The third- and fifth-order susceptibilities were measured using the Z-scan technique in experiments made with the second harmonic of an Nd: YAG laser (532 nm, 80 ps, 7 Hz). The nonlinear optical response of the colloidal system and its dependence with the NPs filling fraction were measured and theoretically described. The analysis of the results using the Maxwell-Garnet model provided a value for the Co3O4 NPs susceptibility. (C) 2012 Optical Society of America
