摘要

Organic light-emitting diodes (OLEDs) with nanostructured fullerene (C-60) ultrathin layers were fabricated. The luminance and efficiency are decreased due to exciton quenching in the OLEDs with C-60 layers at the N,N'-Di (naphth-2-yl)-N, N'-diphenyl-benzidine (NPB)/8-hydroxyquinoline aluminum (Alq(3)) interface. It is opposite to the results reported by Kato [K. Kato, K. Takahashi, K. Suzuki, T. Sato, K. Shinbo, F. Kaneko et al., Curt. Appl. Phys. 5, 2005, 321]. And C-60 ultrathin layers play a role of weak p-type delta-dopant in the NPB layer due to forming of a charge transfer complex C-60(-):NPB+. The current density and luminance are enhanced in the OLEDs with 0.7 nm C-60 ultrathin layers inserted in NPB layer. A suggested explanation is p-type delta-doping effect in the NPB layer which increases the charge mobility of NPB films.
