We used a chemical method to synthesize three kinds of PbS nano-particles. There were different spatial forms in the nano-particles. The part of them were nano-ribbons with different length in shape, other parts were in nano-particles. We measured the nonlinear optical performance of suspension of three kinds of PbS nanoparticles, including nano-ribbons, nano-particles, in ethanol by nonlinear transmission and Z-scan technique with a doubled frequency Nd:YAG laser at 532nm. It was found that the PbS nanoparticles with various spatial structures exhibit good optical limiting performances. The maximum nonlinear refractive index is about 6.96x10-4 cm2/GW, nonlinear absorption coefficient is about 6.98cm./GW.
