Light Emitting Devices
Organic light emitting devices (OLEDs) are a highly promising emissive technology for flat panel displays. OLEDs employ soft organic semiconductors to convert injected charge into luminescent excitons, in a process known as electroluminescence. But in order to be widely adopted, OLEDs must not only match the color purity and long-term stability of competing technologies, they must realize their maximum potential efficiency.

We focus on the efficiency of electroluminescence, and particularly the effects of spin on exciton formation in organic semiconductors. We have studied the fundamental efficiency limits in OLEDs and we are also working on one of the long term obstacles to OLED commercialization: high efficiency blue devices.
