摘要

In this work we employ the Finite Difference Time Domain (FDTD)method to calculate the optical spectra and the intensity of local electromagnetic fieldat the surface of different size, shape and assembling configuration of nanoparticles(NPs) with a view to optimize their sensing activity. We first consider goldnanospheres of 20 nm diameter where analytical solutions are available for comparison.The other shapes we consider include gold nanorods and silver nanoprisms whichare particularly important for applications, because they allow tuning the plasmonresonances across the whole visible and near infrared range. The theoretical spectraare compared with experimental data from synthesized samples in our laboratory.
