| Outline of Final Research Achievements |
We demonstrate an novel pathway for high-efficient fluorescence-based OLEDs by applying the general concept of thermally activated delayed fluorescence (TADF) to a assistant dopant, resulted in the fluorescence-OLEDs showed exciton production efficiency reached nearly 100%. In addition, the enhancement of operational stability compared to that of OLEDs using the TADF molecules as emitters was observed, indicating that the our proposed energy transfer process can provide dual enhancement of both EL efficiency and operational stability in OLEDs by rapid upconversion of triplet excitons.
