This finding is significant, because it is an optimization which does neither involve a change of materials used nor changes to the device architecture. Both are the typical levers for improvements in the field of OLEDs. This concept can universally be explored in every given specific OLED stack, which will be equally appreciated by leading industry. This in particular includes thermally activated delayed fluorescence (TADF) OLEDs, which see a tremendous research and development interest at the moment. Furthermore, the improvements that, as shown by the researchers, can be tracked back to differences on the exciton dynamics on the nanoscale suggest that also other fundamental properties of organic semiconductors (e.g. transport, charge separation, energy transfer) can be equally affected.
