Abstract

Precise rise and decay curves of excimer emissions of poly (N-vinylcarbazole) films in the picosecond time region have been measured by using a time-correlated single photon counting technique. The partial overlap excimer fluorescence was observed immediately after excitation, while the sandwich excimer fluorescence showed delayed formation processes. These results were quite different from those reported before, discussed in terms of high intensity excitation and photo-oxidation effects.
