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 (EQE_max) of 13.5% with a luminance of 17 250 cd m⁻² than the conventional (30 nm) non-doped device.
