Abstract
The mechanics of Forster energy transfer and charge transfer in organic light emitting diodes (OLED) based on 8-hydroxyquinoline aluminum (Alq3) were studied. A soluble derivative of quinacridone, N-N′-di-isoamyl quinacridone (DIQA) was synthesized and was used with Alq3 to dope films of poly(9-vinylcarbazole) (PVK). Measurements of the photoluminescence (PL) and electroluminescence (EL) of the films indicated a more enhanced efficiency that PVK:Alq3 films. However, the optimal DIQA concentration was found to be lower for EL that for PL.
