We have measured the thermo optic coefficient d n /d T and the thermal induced index of refraction n 2 of PbS nanoparticles in organosol with the single beam Z scan technique. The optical limiting properties of PbS nanoparticles were studied under continuous wave laser illumination. Finally, the results obtained were analyzed and discussed.
