Abstract
Charge carrier photogeneration in titanyl phthalocyanine was investiga ted by means of fluorescence and photocurrent measurements, under samp le excitation by two time-separated ultrashort light pulses. Exciton-e xciton annihilation was employed to obtain information on the time cou rse of the fluorescence and generation processes. Charge carriers were found to be generated during only a short time interval after the exc iton was created. This interval is much shorter than the fluorescence state lifetime.
