Nonlinear Optical Properties of Au and Ag NanoparticlesEmbedded into Hybrid-block Copolymer Micelles

摘要

The nonlinear optical (NLO) properties of two classes block-copolymer micelles containing metallic nanoparticles of gold are silver are reported. The NLO properties of the incorporated organic-inorganic materials were determined by means of Optical Kerr Effect (OKE) and Z-scan technique. under 35 ps and 4 ns at 532 nm excitation wavelength. The results showed that the nonlinear response depends on the metallic load of the micelles and from the size of the forming micelles.
