摘要：

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