plasmon resonance - Swedish translation – Linguee

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.

As these plasmons oscillate at specific resonant frequencies, they move with periodic driving forces that can become large amplitude oscillations when they interact. Surface plasmon resonance (SPR) is the manifestation of a resonance effect due to the interaction of conduction electrons of metal nanoparticles with incident photons. The interaction relies on the size and shape of the metal nanoparticles and on the nature and composition of the dispersion medium. Se hela listan på physicsopenlab.org Surface Plasmon Resonance is a phenomenon that occurs when polarized light hits a metal film at the interface of media with different refractive indices. SPR techniques excite and detect collective oscillations of free electrons (known as surface plasmons) via the Kretschmann configuration, in which light is focused onto a metal film through a glass prism and the subsequent reflection is 2018-04-05 · The Surface Plasmon Resonance Effect on the Defect-Mode Cholesteric Liquid Crystals Doped With Gold Nanoparticles Impact Statement: Cholesteric liquid crystals exhibit a photonic bandgap, at edges and defects of which the photon densities are significantly increased. The band gap of hybrid lead halide iodide (CH3NH3PbI3) can be gradually increased by replacing iodide with increasing amounts of bromide, which can not only offer an appreciate solar radiation window for the surface plasmon resonance effect utilization, but also potentially result in a large open circuit voltage.

Because the surface plasmon resonance is a manifestation of a coherent oscillation of the conduction band electrons, the loss of coherence is a form of deactivation of the excited state and it may have observable effects.

We found that the reflectivity of the SPR system was sensitive to the incident angle of light, dielectric constant of the detected samples, wavelength of light, and thickness of the Ag film. It reached an extreme minimal value (EMV) at an extreme angle θ. 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 level of enhancement strongly depends on parameters such as the dielectric constant, distance, particle size, particle shape, and light wavelength, and thus depends on the combination of the materials and the surface state , , . 2005-12-26 · The surface plasmon resonance frequency and the phase jump strongly depend on the wave vector of the evanescent wave, the refractive index of the prism, and the incident angle of the terahertz pulses and the distance between the prism and active material. These features can no longer be explained with conventional Otto's approximation.
