Description:

Triplet–triplet annihilation (TTA) can double the energy of excited states. Therefore, it is utilized for reducing the operation voltage of organic light-emitting diodes (OLEDs). We improved the external quantum efficiency of TTA-based upconversion (UC)-OLED through precise device design. Furthermore, the UC-OLED that can emit blue light was demonstrated.
