Abstract
The mechanism of the charge carrier photogeneration in Y-form titanyl phthalocyanine was investigated by means of fluorescence and photocurr ent measurements. Sample excitation by two time-separated light pulses was applied to obtain information on the time course of the fluoresce nce and generation processes. Charge carrier precursors-charge pairs-w ere found to be generated only during the short time interval after th e exciton was created. This interval is much shorter than the fluoresc ence state lifetime. (C) 1997 American Institute of Physics.
