Abstract

Efficient solution-processed color-stable and color-tunable white organic light emitting diodes (OLEDs) have been realized by judicious selection of the host materials for the emission layers. The color-tunable OLED demonstrates the unique characteristic of modulating the electroluminescence by using the applied voltage of the device and displays color temperatures ranging from 1600 K to 4600 K around the daylight locus, with a peak external quantum efficiency of 13.6% and a peak current efficiency of 22.5 cd A-1. On the other hand, the chromaticity-stable device shows a negligible color change, from 300 to 2000 nits. The manipulation of chromaticity is attributed to the energy transfer dynamics of the hosts and dopants under different electric fields.
