Abstract

Electric field effect on time-resolved exciplex luminescence has been examined in electron donor–acceptor organic solid films of undoped and an organic phosphor PtL2Cl-doped (m-MTDATA:BPT:PC) blends. The applied field leads to a decrease of the initial amplitude and luminescence lifetimes for both singlet and triplet exciplex underlain emission. The largest reduction (up to 50%) of the lifetime has been observed for the triplet exciplex emission and the effect interpreted in terms of the exciplex dissociation into electron–hole pairs driven by hopping separation of such generated charge carriers.
