Improved electroluminescent efficiency of organic light emitting devices by co-doping N, N′-Dimethyl-quinacridone and Coumarin6 in tris-(8-hydroxyquinoline) aluminum

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 20mA∕cm2, superior EL efficiency of 9.33cd∕A was obtained from 1.6% co-doped (0.8% DMQA and 0.8% C6) d...
