对分散在二甲基甲酰胺（DMF）中的硫化镉纳米粒子的非线性光吸收、散射和光限幅特性进行了研究。这些纳米粒子是使用标准化学合成方法，以硫代甘油作为封端剂合成的。研究是在纳秒范围内的532纳米处进行的。发现强双光子吸收和非线性散射是这些纳米粒子具有良好光限幅特性的原因。（C）2005美国光学学会。
The nonlinear optical absorption, scattering and optical limiting properties of CdS nanoparticles dispersed in dimethylformamide (DMF) are investigated. The nanoparticles are synthesized using the standard chemical synthesis method with thioglycerol as the capping agent. The investigations are carried out at 532 nm in the ns regime. Strong two-photon absorption and nonlinear scattering are found to be responsible for good optical limiting characteristics in these nanoparticles. (C) 2005 Optical Society of America.
