利用单光束Z扫描技术测量了PbS纳米微粒溶胶的热光系数dn/dT和热致折射率n2,研究了在连续激光源作用下的光限幅效应,并对实验结果进行了分析与讨论.We have measured the thermo-optic coefficient dn/dT and the thermal-induced index of refraction n2 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.
