Blueshift of the surface plasmon resonance studied with Electron Energy Loss Spectroscopy (EELS)
Abstract
We used monochromated EELS to study the surface plasmon resonance of isolated silver nanoparticles with sizes ranging from 30 nm down to 3 nm. We observe a significant blueshift of 0.5 eV. We compare our experimental data with models going beyond the Drude model including the response of inhomogeneous electron density at the surface of noble metallic particles. We discuss the potential implications of this blueshift for nanometer scale plasmonic silver structures in general.<br/>
