Nanoplasmonic surfaces enabling strong surface-normal electric field enhancement.
Conventional two-dimensional (2D) plasmonic arrays provide electric field intensity enhancement in the plane, typically with a surface coverage around 50% in the plan-view. Here, we show nanoplasmonic three-dimensional (3D) surfaces with 100% surface coverage enabling strong surface-normal field enhancement. Experimental measurements are found to agree well with the full electromagnetic solutio...

متن کاملNanoplasmonic enhancement of single-molecule fluorescence
We demonstrate that the fluorescence rate from a single molecule with near-unity quantum yield can be enhanced by a factor of ≈10 by use of a single laser-irradiated noble metal nanoparticle. The increased fluorescence rate is primarily the result of the local field enhancement. However, at particle–molecule distances shorter than 2 nm, nonradiative decay of the excited molecule due to energy t...
متن کاملNanoplasmonic renormalization and enhancement of Coulomb interactions
In this paper, we propose a general and powerful theory of the plasmonic enhancement of the many-body phenomena resulting in a closed expression for the surface plasmon-dressed Coulomb interaction. We illustrate this theory by computing the dressed interaction explicitly for an important example of metal–dielectric nanoshells which exhibits a rich resonant behavior in magnitude and phase. This ...
