Researchers at Kyushu University have increased the lifetime of OLEDs based on thermally activated delayed fluorescence (TADF). TADF, a process demonstrated at Kyushu University’s Center for Organic Photonic and Electronics Research (OPERA) in 2012, allows fluorescent molecules (which can be metal-free) to approach the theoretical 100% charge conversion of phosphorescent materials which need to include expensive ...
