Abstract

We report highly efficient, ultrathin non-doped green and bluish-green organic light-emitting diodes (OLEDs) using a thermally activated delayed fluorescence (TADF) emitter. The green OLED with an ultrathin (�1 nm) EML showed a 2.6-fold higher external quantum efficiency (EQEmax) of 13.5 with a luminance of 17�250 cd m�2than the conventional (30 nm) non-doped device. © The Royal Society of Chemistry 2021.
