Abstract

Circularly polarized light emitted from OLEDs exhibits opposite handedness depending on the propagation direction of the light. Switching the current flow in the OLED also switches the light handedness.

Discussions

• Working together with a theoretician, Binghai Yan, we termed this new emission mechanism 'anomalous' and explained it through the effect the chiral medium has on charge carrier angular momentum. doi.o [bsky, 1 points, 1 comments]
