Experimental realization of subradiant, superradiant, and fano resonances in ring/disk plasmonic nanocavities.

ACS nano

Sonnefraud Y, Verellen N, Sobhani H, Vandenbosch GA, Moshchalkov VV, Van Dorpe P, Nordlander P, Maier SA.
PMID: 20155967
ACS Nano. 2010 Mar 23;4(3):1664-70. doi: 10.1021/nn901580r.

Subradiant and superradiant plasmon modes in concentric ring/disk nanocavities are experimentally observed. The subradiance is obtained through an overall reduction of the total dipole moment of the hybridized mode due to antisymmetric coupling of the dipole moments of the...

Recently, aluminum has been established as an earth-abundant alternative to gold and silver for plasmonic applications. Particularly, aluminum nanocrystals have shown to be promising plasmonic photocatalysts, especially when coupled with catalytic metals or oxides into "antenna-reactor" heterostructures. Here, a...

Efficient photocatalysis requires multifunctional materials that absorb photons and generate energetic charge carriers at catalytic active sites to facilitate a desired chemical reaction. Antenna-reactor complexes are an emerging multifunctional photocatalytic structure where the strong, localized near field of the...

Chromatic devices such as flat panel displays could, in principle, be substantially improved by incorporating aluminum plasmonic nanostructures instead of conventional chromophores that are susceptible to photobleaching. In nanostructure form, aluminum is capable of producing colors that span the...
