Researchers from the University of Cambridge, the University of East Anglia and the University of Eastern Finland developed soluble carbene-metal-amides light emitting materials that were found to be very efficient and reach an internal quantum efficiency of nearly 100% at high brightness.
The new materials look like propellers and the rotation of the molecules changes the light emitting efficiency. Those materials are made from copper or gold, but the researchers aim to find similarly-shaped materials that are free from rare elements.
