Fluorescence Enhancement via Dual Coupling of Dye Molecules with Silver Nanostructures
Chemosensors, 2021 We demonstrate the enhancement of fluorescence emitted from dye molecules coupled with two surface plasmons, i.e., silver nanoparticles (AgNPs)-induced localized surface plasmons (LSP) and thin silver (Ag) film supported surface plasmons.

Metal-in-metal localized surface plasmon resonance [PDF]
Nanotechnology, 2009 Anomalous strong resonances in silver and gold nanoporous thin films which conduct are found to arise from isolated metal nano-islands separated from the surrounding percolating metal network by a thin loop of insulator. This observed resonant optical response is modelled.

Light‐Controlled Reversible Coassembly of Hybrid Functional Nanostructures
Advanced Functional Materials, EarlyView.Light‐responsive hybrid nanostructures are formed by coassembling azobenzene‐ and PAH‐functionalized nanoparticles through reversible an tunable π interactions. The system enables tunable coupling between distinct components such as gold and magnetite or carbon nanotubes, producing switchable optical and magnetic properties under light and magnetic ...

Transverse Anderson localization of surface plasmon polaritons [PDF]
Optics Letters, 2017 We investigate the effect of disorder on the propagation of surface plasmon polaritons in arrays of evanescently coupled dielectric loaded surface plasmon polariton waveguides. Diagonal disorder is implemented by randomly varying the heights of the waveguides.

Visible quantum plasmonics from metallic nanodimers
, 2016 We report theoretical evidence that bulk nonlinear materials weakly interacting with highly localized plasmonic modes in ultra-sub-wavelength metallic nanostructures can lead to nonlinear effects at the single plasmon level in the visible range.
