White Organic Light‐Emitting Diodes Based on Quench‐Resistant Fluorescent Organophosphorus Dopants

Abstract

Abstract The control of the doping ratio of a blue‐emitting matrix by an orange emitter with high accuracy still remains very challenging in the development of reproducible white organic light‐emitting diodes (WOLEDs). In this work, the development of an organophosphorus dopant that presents a high doping rate in order to reach white emission is reported. The increase of the doping rate has a small impact on the CIE co‐ordinates and on the EQE. These results are very appealing towards the development of “easy‐to‐make” WOLEDS.
