Hajime Nakanotani, High Efficiency Organic Light-Emitting Diodes with Fluorescent Emitters, Taiwan Solid State Lighting Symposium, 2015.03, Fluorescence-based organic light-emitting diodes (OLEDs) have continued to attract interest because of their long operational lifetimes, high color purity of electroluminescence (EL), and potential to be manufactured at low-cost in next generation full-color display and lighting applications. In fluorescent molecules, however, the exciton production efficiency is limited to 25% due to the deactivation of triplet excitons. Here, 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 high external EL quantum efficiencies of 13.4 - 18.0% for blue, green, yellow, and red emission, indicating that the exciton production efficiency reached nearly 100%.. |
