Abstract

Au/Ag nanoshuttles with sharp tips at both ends have been synthesized in glycine solution by chemically depositing silver on gold nanorods. Strong local field in the Au/Ag nanoshuttles enhanced by longitudinal surface plasmon resonance (LSPR) were investigated by theoretical calculations and experimental measurements. At the corresponding LSPR wavelengths, the extinction cross section and nonlinear refraction of the Au/Ag nanoshuttles are about 1.5 and 8.0 times of those of the original Au nanorods, respectively.
