Abstract

Exciplex fluorescence of poly(N-vinylcarbazole) films doped with dimethyl terephthalate and p-dicyanobenzene was investigated by using the nanosecond time-correlated single-photon-counting method. The fluorescence peak in the time-resolved spectra shifted continuously to the long wavelength with time. The exciplex fluorescence showed nonexponential decays with slow tails up to the microsecond time region, and the decay process was enhanced by applying an electric field. New mechanisms underlying these results were considered.
