Abstract

original image

A new way to improve organic white-light-emitting-diodes is reported. Their emissive layers are unique in that three different emissive states are produced efficiently at the same time (see scheme). The combined emission band enables us to form an efficient white device with particularly high color rendering index of CRI=90.
