| contents | Organic light-emitting diodes (OLEDs) have redefined lighting with their environment-friendliness and flexibility. However, only 25 % of the electronic states of organic molecules can emit light upon electrical excitation, limiting the overall efficiency of OLEDs. Strong light-matter coupling, achieved by confining light within OLEDs using mirrors, creates hybrid light-matter states known as polaritons, which could "activate" the remaining 75 % electronic triplet states. Here, we study triplet-to-polariton transition and derive rates for both reverse inter-system crossing and triplet-triplet annihilation. In addition, we explore how the harmful singlet-singlet annihilation could be reduced with strong coupling. |
