Abstract
An active light-emitting layer composition including a thermally activated delayed fluorescence (TADF) molecule with TADF properties as a host material and a luminescent molecule with circularly polarized (CP) properties as a dopant. Also, a light-emitting device, such as an organic light-emitting diodes (OLED), including the active light-emitting layer made of this composition.
Claims13
