2014-12-11 · In this paper we provide a mathematical framework for localized plasmon resonance of nanoparticles. Using layer potential techniques associated with the full Maxwell equations, we derive small-volume expansions for the electromagnetic fields, which are uniformly valid with respect to the nanoparticle's bulk electron relaxation rate. Then, we discuss the scattering and absorption enhancements

Issue Date: April 2016 A special characteristic of the optic al properties of metal nanoparticles (NPs) is the existence of localized surface plasmon resonance [1–5]. Se hela listan på cleanenergywiki.org 2008-08-30 · Surface plasmon resonance induced by silver nanoparticles increases the absorption coefficient of the dye in dye-sensitized solar cells , , . 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] . For polyhedral nanoparticles, the surface plasmon resonances are studied as a function of the number of faces and vertices.

2011-12-04 · In the figure the wave number of the surface plasmon wave is always larger than the photon wave number and hence the photon would not be able to excite surface plasmon. The dispersion curve of the photon and surface plasmon wave must cross each other as shown in Figure 1 .b [ 2 , 20 ] for surface plasmon resonance to occur when the momentum of incoming light is equal to momentum of the plasmons.

2017-04-20 · 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. Localized surface plasmon resonance (LSPR) fiber-optic sensors have been widely investigated in recent years for biomolecule analysis [1,2], since the surface metallic nanoparticle arrays are extremely sensitive to the refractive index (RI) variation of the surrounding medium [3,4], which includes but is not restricted to their applications in antigen–antibody interactions [5,6] and biotin The origin of the surface plasmon resonance and synthesis procedures are described.
