Work by leading OLED researchers has repeatedly demonstrated that phosphorescent OLED performance is not limited to 25% of the relaxation pathways that produce photonic emissions, owing to statistical spin of excited states normally associated with singlets. Phosphorescence is routinely used in the laboratory to fabricate phosphorescent OLEDs with performance surpassing 80%. This project will explore novel radiative decay control techniques to harness the energy of triplet states that are chemically and quantum-mechanically different, but functionally similar to currently accepted phosphorescent methods. The three-year project will systematically explore blending of chromophores and different plasmon structures to achieve better efficiencies via enhanced triplet annihilation and utilization.
