Inserting Buffer Layers for Carrier Balance Configurations in Hyperfluorescence-Based OLEDs

Description:

OLEDs, containing non-doped emissive layers as buffer layers, restored their device characteristics of red, green hyperfluorescence, and blue triplet–triplet fusion. These features degraded owing to carriers accumulated at the heterostructures. We considered the built-in voltage and?nonradiative recombination processes as the effects of disturbing carrier balance.
