Rev. Lett. 21, 1530 – Published 25 November 1968 表面プラズモン共鳴(ひょうめんプラズモンきょうめい、英: Surface Plasmon Resonance、略称:SPR)とは、固体あるいは液体中の電子が、それらに入射した光によって集団振動を誘導される現象、あるいは、その集団振動のことである。共鳴条件は、光量子(フォトン)の周波数が表面電子の自然周波数と一致する時に達成される。ナノメートルサイズの構造における plasmon resonance can be found in refs 17, 19, and 20. We use the dielectric constant of bulk Au as measured by Johnson and Christy.21 As is known, the plasmon resonance is sensitive to the surrounding medium, and the ITO glass substrate has a strong effect on the plasmon resonant wavelength.20 Instead of attempting a complete solution, Enhanced photocatalytic activity, which can be demonstrated by the surface plasmon resonance (SPR) effect induced by Au NPs, occurred and was further confirmed to be associated with the different loading densities of Au NPs. These discoveries use solar water splitting as a platform and provide ideas for exploring the mechanism of SPR enhancement. Blueshift of the surface plasmon resonance in silver nanoparticles: substrate effects Søren Raza,1,2 Wei Yan,1,3 Nicolas Stenger,1,3 Martijn Wubs,1,3 and N. Asger Mortensen1,3,∗ 1Department of Photonics Engineering, Technical University of Denmark, DK-2800 Kgs. Lyngby, Denmark 2Center for Electron Nanoscopy, Technical University of Denmark 2017-09-26 · The surface plasmon resonance (SPR) with the bimetallic film can achieve minimum reflectivity and higher evanescent field enhancement than the SPR configuration with the single gold film, which makes it to be a much better option for enhancing the photonic Spin Hall Effect (SHE). It is found that the thicknesses of silver and gold films have a major impact on the photonic SHE, and the maximal All-fiber phase modulator and switch based on local surface plasmon resonance effect of the gold nanoparticles embedded in gel membrane Luo, Meng Yang, Xinghua This research focuses on the side-polished Single-Mode Optical Fibers (SMOF) as refractive index (RI) sensor utilizing properties of Surface Plasmon Resonance. The SMOF with cladding stripped off shows a D-shaped optical fiber with high sensitivity functionalization. Here we show silver protected by graphene oxide (GO) as viable candidates.

Plasmon resonance effect

The localized surface plasmon resonances in a metallic nanorod are determined using the “electrostatic approximation” and by a finite-difference time-domain numerical solution of Maxwell’s equations. The difference between the two methods is related to the effects of re-radiation, or retardation, which is not included in the electrostatic formulation. 2021-01-07 By taking advantage of the local surface plasmon resonance effect of gold nanoparticles embedded in the agarose membrane, under the excitation of near-infrared region light, the gold nanoparticles were excited to change the effective refractive index of one arm of the Mach–Zehnder interferometer.

2008-09-29 2017-04-20 SPR based biosensors are explained. 1968-11-01 Surface plasmon resonance (SPR) is linked with many factors, like size, shape and surface chemistry of particle, and of course it is also affected by the solvent medium in which particles are 2005-12-26 Surface Plasmon Resonance Effect in Inverted Perovskite .

The interaction relies on the size and shape of the metal nanoparticles and on the nature and composition of the dispersion medium. Plasmonics SPR (surface plasmon resonance) is a physical process that is observed when polarized light hits a metal film under conditions of total internal reflection. Surface Plasmon Resonance is a phenomenon that occurs when polarized light hits a metal film at the interface of media with different refractive indices.
