Outline of Final Research Achievements

In this study, I have proposed new idea that enables determination of ionization energy of transient species, i.e., excited singlet state and triplet state, of organic semiconducting thin films, so-called time-resolved two photon photoelectron yield spectroscopy (2P-PYS). By constructing a prototype of the experimental set-up of 2P-PYS, I tested the idea by using pentacene thin films grown on ITO substrates. Using Nd:YAG sub-ns pulse laser, I confirmed that the detection of photoelectron emission is possible from an excited triplet state of the thin films. Further, I revealed that the very intense pulse laser is problematic to determine the energy of the excited state. An appropriate intense pulse laser and experimental condition are needed to be found for the next and final step.
