Paper Abstract

We discuss recent observations of a metal-proximity-induced fluorescence and phosphorescence of C60 molecules and the key roles that are played in the phenomenon by the metal-induced lowering of the symmetry of the molecules, and the exchange Coulomb spin-flipping scattering and virtual electron hopping (superexchange) between the triplet excitons of the C60 molecules and the electrons in the metal, which lead to a mixing of the singlet and triplet excitons. The enhancement of phosphorescence by the mixing of singlet and triplet exciton states via their exchange interactions with the electrons in the substrate should in general also occur for molecules in close proximity to surfaces having atoms or molecules with incompletely filled outer shells.
