Title of Paper:

Tuning the wavelength drift between resonance light absorption and scattering of plasmonic nanoparticle

Journal:

APPLIED PHYSICS LETTERS

Summary:

Local surface plasmon resonance in a metallic nanoparticle can induce intense light absorption and
scattering simultaneously. However, the light absorption does not always have the same resonance
wavelength with the scattering. Both the red and blue drifts of the scattering peak from the
absorption peak are observed in the dielectric coated gold nanosphere, gold nanoshell, and
nanorod. The wavelength drift between the absorption and scattering has been optimized by
changing the particle shape and structure. This tunable wavelength drift can be used in selecting
the resonance absorption or scattering for optical applications by altering the incident wavelength.
