| 英文摘要 | 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. |
