Abstract:

Plasmon resonances in metallic nanoparticles augment the Förster resonance

energy transfer (FRET) between two molecules. We calculate and analyze comparatively

the enhancement factors of FRET for a metallic nanosphere and for a metallic spherical

nanoshell by finite element method (FEM). These calculations are compared with analytical

results obtained from the knowledge of spectral properties of the Neumann-Poincaré

(electrostatic) operator for sphere. With respect to the plain metallic nanosphere, the

spherical nanoshell shows a greater tunability of energy range for which the energy transfer

is enhanced. Our work can be relevant for using FRET for various applications regarding

porous materials.
