Abstract Among the three primary colors, blue emission in organic light-emitting diodes (OLEDs) are highly important but very difficult to develop. OLEDs have already been commercialized; however, blue OLEDs have the problem of requiring a high appli

Organic light-emitting diodes (OLEDs) that produce exciplexes in a bilayer are device structures that can dramatically reduce the turn-on voltage. In this study, we report that this device structure contributes to an impressive improvement in operati

Spatial distribution of triplet excitons near the organic semiconductor interface is clarified. The result indicates that 90% of the triplet excitons are confined to less than 10 nm from the interface, where photoelectric conversion and charge recomb
