Abstract

We report measurements of the nonlinear refractive index, n 2 , of nickel oxide nanoparticles (NPs) in toluene at 532 nm . The measurements were performed using the Z-scan technique with 80 ps laser pulses at 7 Hz . Large values of n 2 in the range of 10 13 10 12 cm 2 W were measured, and negligible two-photon absorption coefficient was estimated for colloids having NP filling fractions in the range of 10 8 10 7 .
