Intriguing Optical Properties of Plasmonic Nanostructures

Abstract
A new method for size-controlled synthesis of chemically clean silver
nanoparticles ranging
in size from 5 to 400 nm will be introduced. The optical properties
of nanoparticles will be
discussed in terms of extinction, absorption, and scattering cross
sections and efficiencies.
The extension of the local field from the surface of the particles
was experimentally measured
for the first time. A new phenomenon, coherent quadrupole coupling
of plasmon resonances
in two dimensional arrays of the nanoparticles was observed and its
implication for plasmonic
computing and advanced sensing will be discussed.
