Abstract


Small aggregates of plasmonic nanoparticle are known to sustain large surface enhanced Raman scattering (SERS) signals due to coupling of localized surface plasmon reosnances (LSPR) induced by the excitation radiation. Experimental measurements and theoretical calculations have both shown the intricate dependency of LSPR on individual nanoparticle structures. Very few studies have examined the correlation between SERS, LSPR and the structural geometry of small nanoparticle aggregates extensively. In thisĀ  paper we will discuss results from our recent studies of the correlation between the geometry of small nanoparticle aggregates and their optical properties (SERS and LSPR).
