(a) Extinction spectra of the individual gold nanorod and a notched triangle nanoslice. Here, E shows the polarization of the electric field, and the propagation direction of plane wave is along −z axis. The electric field distributions of the individual notched triangle nanoslice for the resonant peaks at (b) 630 nm, (c) 680 nm, (d) 720 nm, respectively. (e) The electric field distributions of individual gold nanorod for the resonant peaks at 680 nm.
