By theoretically investigating the optical behavior of one-dimensional gold nanogratings using Fourier Modal Method, we have shown that both integer and non-integer multiples of surface plasmon polariton wavelengths should be taken into consideration in sp ...
The present invention relates to a plasmonic biosensor system. The system includes a nano-hole array device comprising at least one nano-hole array (NHA) including at least one or a plurality of nano holes (NH), an image sensor (A3) for capturing light pro ...
Second harmonic (SH) generation (SHG) in plasmonic nanostructures originates from the surface of centrosymmetric metals where inversion symmetry is broken. The interest in that topic stems from the strong near-field enhancement on the surface of plasmonic ...
Harvesting nonequilibrium hot carriers from plasmonic-metal nanostructures offers unique opportunities for driving photochemical reactions at the nanoscale. Despite numerous examples of hot electron-driven processes, the realization of plasmonic systems ca ...
Nanoplasmonic devices have become a paradigm for biomolecular detection enabled by enhanced light–matter interactions in the fields from biological and pharmaceutical research to medical diagnostics and global health. In this work, we present a bright-fiel ...
We present optical absorption spectra from the ultraviolet to the visible for size selected neutral Ag-n clusters (n = 5-120) embedded in solid Ne. We compare the spectra to time-dependent density functional calculations (TDDFT) that address the influence ...
The plasmonic response of gold can be utilized to enhance the incident electromagnetic (EM) field by several orders of magnitude. When a gold nanoparticle is placed in close proximity to a gold film, the incident field can excite a deeply confined plasmon, ...
Metal nanoparticles are frequently employed for the colorimetric detection of specific target molecules using an aggregation-induced shift of the localized surface plasmon resonance. However, metal nanoparticles dispersed in bulk solutions are prone to be ...
Plasmonic hot carrier devices extract excited carriers from metal nanostructures before equilibration and have the potential to surpass semiconductor light absorbers. However their efficiencies have so far remained well below theoretical limits, which nece ...
We investigate optical second-harmonic generation (SHG) from metasurfaces where noncentrosymmetric V-shaped gold nanoparticles are ordered into regular array configurations. In contrast to expectations, a substantial enhancement of the SHG signal is observ ...
