Abstract

We have employed two-photon photoemission (2PPE) spectroscopy to observe photoinduced charge transfer at C₆₀ fullerene thin films formed on graphite and Au(111) substrates. From the analysis of the 2PPE intensities of molecular-derived unoccupied states, it is revealed that the photoexcited electron transfer from graphite substrate to C₆₀ is suppressed compared to C₆₀ on Au(111), owing to inert properties of graphite surfaces.
