Theoretically, this effect can be attributed to the enhancement of the local electromagnetic field near the metal surface when the wavelength of the irradiation source is coincident with the optical absorption of the surface plasmon [4] , [5] .

SPR is the basis of many standard tools for measuring adsorption of material onto planar metal surfaces or onto the surface of metal nanoparticles.

Expanding localized surface plasmon resonance (LSPR) towards long wavelengths has been the focus of plasmonics for several decades. Compared with the most studied Au and Ag nanoparticles, Cu nanoparticles have intrinsic long-wavelength LSPR, but hard to be facially fabricated due to their sensitivity to oxidation.

Modified Au-Based Nanomaterials Studied by Surface

in zinc NPs [18–24] obtained by differe nt In the last two decades, plasmon resonance in gold nanoparticles (Au NPs) has been the subject of intense research efforts. Plasmon physics is intriguing and its precise modelling proved to be challenging. In fact, plasmons are highly responsive to a multitude of factors, either intrinsic to the Au NPs or from the environment, and recently the need emerged for the correction of standard The basis for the effect is the plasmon resonance of the free electrons in the metal nanoparticle, which can be understood by studying the polarizability (the ease with which charges, such as the conduction electrons on the metal nanoparticle surface, undergo charge distribution and form partial dipoles).

Plasmon physics is intriguing and its precise modelling proved to be challenging.

The temporal analysis of plasmon resonance modes can be very instrumental in the area of light controllability of plasmon resonances in semiconductor nanoparticles [8,9], where proper time synchronizations of excitations of specific plasmon modes may be needed.In this Letter, we present a self-consistent theoretical technique for the temporal analysis of specific plasmon modes in nanoparticles … An overview of surface plasmon resonance (SPR) About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features © 2021 Google LLC Nanoparticles often have unexpected visible properties because they are small enough to confine their electrons and produce quantum effects. The optical properties of a metallic nanoparticle depend mainly on its surface plasmon resonance, where the plasmon refers to the collective oscillation of the free electrons within the metallic nanoparticle.
