Applications of Plasmon-Enhanced Nanocatalysis to Organic Transformations.

Chemical Reviews, 2019
Localized surface plasmon resonance (LSPR) is a physical phenomenon exhibited by nanoparticles of metals including coinage metals, alkali metals, aluminum, and some semiconductors which translates into electromagnetic, thermal, and chemical properties ...

Surface Plasmons and Plasmonics

2020
Surface plasmons (SPs) correspond to self-sustaining excitations of the electron gas of metals or semiconductors, i. e., to modulations of the density of such gas occurring at the surface of the body generating electric fields propagating along the surface and decaying exponentially perpendicular to it.

Focusing Surface Plasmons with a Plasmonic Lens

Nano Letters, 2005
We report the focusing of surface plasmon polaritons by circular and elliptical structures milled into optically thick metallic films or plasmonic lenses. Both theoretical and experimental data for the electromagnetic nearfield is presented. The nearfield is mapped experimentally using nearfield scanning optical microscopy and plasmonic lithography. We

About plasmons and plasmonics in graphene

2015 17th International Conference on Transparent Optical Networks (ICTON), 2015
A number of recent experimental and theoretical studies indicate the existence of THz plasmons in graphene. It is also suggested that the existence of such plasmons should be a generic property of ideal graphene, allowing for the generation of surface plasmons, which are the basis of modern plasmonics technologies. We have approached the problem from a

Aluminum for Plasmonics [PDF]

ACS Nano, 2013
Unlike silver and gold, aluminum has material properties that enable strong plasmon resonances spanning much of the visible region of the spectrum and into the ultraviolet. This extended response, combined with its natural abundance, low cost, and amenability to manufacturing processes, makes aluminum a highly promising material for commercial ...

Damping of plasmons in graphene

Nature Photonics, 2013
The damping of surface plasmons hinders the realization of nanophotonic devices. Researchers have now uncovered some of the mid-infrared damping mechanisms for plasmons in graphene, which offer a number of unique and interesting properties.

Gold and silver nanoparticles in sensing and imaging: sensitivity of plasmon response to size, shape, and metal composition.

Journal of Physical Chemistry B, 2006
Plasmonic metal nanoparticles have great potential for chemical and biological sensor applications, due to their sensitive spectral response to the local environment of the nanoparticle surface and ease of monitoring the light signal due to their strong ...
