Scientists investigate free electrons and the resonant interactions of electromagnetic waves in the field of plasmonics. However, the discipline still remains to be extended to large-scale commercial applications due to the loss-associated with plasmonic materials. While organic light-emitting devices (OLEDs) are incorporated into mass-scale commercial products due to properties such as good color saturation, versatile form factor and low-power consumption, their efficacy and stability remain to be optimized. During its function, OLEDs accumulate localized build-up of slow-decaying, triplet excitons and charges, which gradually reduce the brightness of the device in an "aging" process, which can then cause a burn-in effect on the display. As a result, it is important to improve the performance of the OLED technology.
