Probing the optical near field of a nanolens

Published

Journal Article

Dielectric core-metal shell nanoparticles, known as metal nanoshells, were shown to possess broadly tunable plasmon resonances whose frequency can be controlled by the relative thickness of the nanoparticle layers. As such, the "nanolens" was characterized by measuring the local electromagnetic field at the nanoshell surface as a function of the nanoparticle's core and shell dimensions via the Surface Enhanced Raman Scattering (SERS) response from a monolayer of nonresonant adsorbate molecules bound to the nanoparticle surface.
