摘要	Electroluminescent (EL) efficiency of organic light emitting devices was improved by co-doping N, N -dimethyl-quinacridone (DMQA) and Coumarin6 (C6) in tris-(8-hydroxyquinoline) aluminum (Alq3). At 20 mA cm2, superior EL efficiency of 9.33 cdA was obtained from 1.6% co-doped (0.8% DMQA and 0.8% C6) device, much higher than those of single-doped devices based on 1.6% DMQA (5.0 cdA) or 1.6% C6 (6.0 cdA). EL efficiency of the single-doped devices with optimal dopant concentration, 0.8% in both cases, are merely 7.13 cdA for DMQA and 6.43 cdA for 0.8% C6, respectively. The significant improvement could be attributed to effective utilization of the host energy and depression of concentration quenching. The co-doping technique provides an effective way to overcome the notorious concentration quenching and hence to improve the EL efficiency. 2005 American Institute of Physics.
