[13a-B409-3] Second harmonic generations from trimaric Au nanostructures
Keywords:Second harmonic generations
We present second harmonic generations (SHG) in dolman-type Au nanoparticle structure. The dolman-type Au nanoparticle structure consists of the three Au nanoparticles, in which their plasmon polarizations are hybridized through near-field coupling. we obtained the efficient SHG signals by resonantly exciting the hybridized mode in the dolman-type structure was approximately 5 times higher than that from the single Au nanoparticle system.
