Emission quenching of magnetic dipole transitions near an absorbing nanoparticle (Conference Presentation)
Author(s): Dmitry N. Chigrin; Deepu Kumar; Gero von Plessen

Paper Abstract

Emission quenching is analysed at nanometer distances from the surface of an absorbing nanoparticle. It is demonstrated that emission quenching at small distances to the surface is much weaker for magnetic-dipole (MD) than for electric-dipole (ED) transitions. This difference is explained by the fact that the electric field induced by a magnetic dipole has a weaker distance dependence than the electric field of an electric dipole. It is also demonstrated that in the extreme near-field regime the non-locality of the optical response of the metal results in additional emission quenching for both ED and MD transitions.
