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.

Au/TiO2 could use the enhanced electric field amplitude on the surface of the Au particle in the spectral vicinity of its plasmon resonance and thus improve the photoactivity. Experimental results show that the synergistic effect between UV and green light for the improvement of photoactivity increases with increasing the SPR absorption, which in turn is affected by the Au content and TiO2 size. This size dependence of the plasmon resonance results from a number of effects, 4–6 of which two are especially important: a spill out of the conduction s electrons beyond the classical particle radius leads to a red shift with respect to the classical description whereas as a reduced s-d screening in the surface region in the case of the noble metals leads to a blue shift. 2008-08-30 This video explains what Surface Plasmon Resonance technology is, how it is used to detect small molecules and their interaction with other proteins.For more 2020-01-01 The other one results from the fact that (in most experiments) not all particles have the same spectra and therefore you observe a superposition (mixture).

These features can no longer be explained with conventional Otto's approximation. Se hela listan på cleanenergywiki.org 2017-04-20 · The coupling between plasmonic and excitonic modes is possible in these hybrid systems, resulting in mixed plasmon/exciton resonances called 'plexcitons' [ 72, 73 ]. In plexcitons, Rabi splitting of the plasmon and exciton resonances occurs, i.e. a spectral shift in opposite directions of the two resonances [ 72 ].

It is a physical Detection of organic materials or heavy ions using the surface plasmon resonance (SPR) effect of the MoS2/Ag system was studies. 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. Temperature effects on surface plasmon resonance: design considerations for an optical temperature sensor Abstract: We present a detailed discussion of the three-interface surface plasmon resonance (SPR) geometry with the "angular interrogation" approach, and study the effect of thermal changes on the SPR curve through numerical simulations. 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.
