Paper Abstract

A device structure that enables the combination of phosphorescent green and fluorescent blue emitters in a solution processed polymer organic light-emitting diode device has been developed. Results demonstrate that it is possible to tune the color of emission by appropriate formulation of the polymers that are used. This enabled the development of a warm white device that had CIE coordinates of (0.462, 0.426), and an external quantum efficiency (EQE) of 13.1%. This EQE was limited by the efficiencies of the emitters used rather than through any internal quenching, and thus the device structure offers potential for further development.
