Paper Abstract

We study localized-surface plasmon resonance (LSPR) and the surface-enhanced Raman scattering (SERS) gain of gold cylindrical and ellipsoidal nanorods of different diameter or major axis. The LSPR and SERS gains are calculated with the three dimensional Finite-Difference Time-Domain method using Drude-Lorentz dispersion model. We find that the maxima of the extinction spectrum and the average SERS gain of each investigated nanostructures are shifted whatever their size and their shape.
