Popis: |
We demonstrate high-efficiency, low-voltage phosphorescent OLED devices (PHOLEDs) using mixed host materials in the light-emitting layer (LEL) and novel formulations in the electrontransporting/ electron-injecting layers (ETL/EIL). The LEL architecture offers significant improvement in efficiency and voltage compared to conventional phosphorescent OLEDs with carbazole-based hosts. Further voltage reduction in our PHOLEDs is achieved through use of a novel material formulation in the ETL and EIL. |
