| 摘 要： | In this paper, the electroluminescence quenching mechanismin a 5,6,11,12-tetraphenylnaphthacene (Rubrene) doped host--guestsystem is studied by utilizing a specially designed organiclight-emitting diode with an emission layer consisting of a fewperiodic host/guest structures. Tris-(8-hydroxyquinoline) aluminium(Alq3) and Rubrene are used as the host and the guest,respectively. The thickness variation of the guest layer in eachperiod enables the study of the effect of molecule aggregation, andthe thickness variation of the host layer suggests a long rangequenching mechanism of dipole--dipole interaction. The long rangequenching mechanism is a F?rster process, and the F?rsterradius of Rubrene is between 3 and 10~nm.
