Notes:
Charge carrier photogeneration in titanyl phthalocyanine was investigated by means of fluorescence and photocurrent measurements, under sample excitation by two time-separated ultrashort light pulses. Exciton-exciton annihilation was employed to obtain information on the time course of the fluorescence and generation processes. Charge carriers were found to be generated during only a short time interval after the exciton was created. This interval is much shorter than the fluorescence state lifetime.
