Recent breakthroughs in thermally activated delayed fluorescence organic light emitting diodes containing non-doped emitting layers

Abstract

Despite the high performance of OLEDs consisting of host–guest blend systems in the emissive layer, OLEDs containing a single molecule as an emitter in the emissive layer (<italic>i.e.</italic> non-doped OLEDs) have significant advantages including easy fabrication procedures and enhanced device stability.
