Intramolecular. uorescence and phosphorescence associated with the transitions between the lowest electronic excited state and ground state of C-70 molecules are identified, leading to unambiguous chemical recognition on the nanoscale. Moreover we demonstrate that the molecular luminescence is selectively enhanced by localized surface plasmons in the STM tip-sample gap.
