Promising interlayer sensitization strategy for the construction of high-performance blue hyperfluorescence OLEDs
0
Multi-resonance thermally activated delayed fluorescence (MR-TADF) materials are promising candidates for organic light-emitting diodes (OLEDs) with narrow electroluminescence (EL) spectra. Scientists in China propose an interlayer sensitization strategy to improve EL efficiencies of blue MR-TADF emitters with blue MR-TADF sensitizer, and successfully realize blue hyperfluorescence OLEDs with high color quality and outstanding EL efficiencies simultaneously.
