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 (Alq(3)). At 20 mA/cm(2), superior EL efficiency of 9.33 cd/A 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 (similar to 5.0 cd/A) or 1.6% C6 (similar to 6.0 cd/A). EL efficiency of the single-doped devices with optimal dopant concentration, 0.8% in both cases, are merely 7.13 cd/A for DMQA and 6.43 cd/A 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.
