As a strategy to reduce the OLED drive voltage, which has been a challenge, we have reported exciplex upconversion-type OLEDs (ExUC)-OLEDs have been reported.In this study, the relationship between the intermolecular distance of the upconversion (UC) layer and the donor layer rubrene, the exciplex formation and TTU is investigated.
