Paper Abstract

The second harmonic generations (SHG) from Au nanorods coated with the nonlinear optical (NLO) polymers will be presented. The thin films of the NLO polymers with the different transition frequencies were prepared. The SHG conversion efficiencies were highly enhanced by coating the NLO polymers on the nanorods. The conversion efficiencies were higher, as the transition wavelengths of the NLO polymers were closer either to the pump light wavelength or its second harmonic wavelength. About five-fold enhancement in the conversion efficiency was recorded from the nanorods of which absorption peak was almost exactly resonant to the second harmonic wavelength, comparing with that from the pristine PMMA coated nanorods.
