| Research Abstract |
Lateral inhomogeneity of organic films is frequently troublesome for high-resolution spectroscopy. We have improved the microspot two-photon photoemission spectrometer and applied it to investigate unoccupied states of organic films. The dispersions of the unoccupied levels of lead phthalocyanine film on HOPG were successfully measured. The time-resolved experiment revealed scattering processes of electrons and holes formed by photoexcitation. We have found an enhanced electronic excitation of rubrene molecules mediated by the image potential state.
