Electroluminescence in Solid-State Lighting and Display Technologies

Organic light-emitting diodes (OLEDs) offer tremendous potential for use in full-color displays and solid-state lighting. To fabricate more efficient and less expensive devices that produce strong luminescence, a better understanding of the electronic and optical processes in OLEDs is essential. To address these issues, we investigate numerous aspects, including: charge and energy transfer; aggregation effects on the electronic structure of the ground and excited states; electronic properties of host and guest materials; and spin-orbit effects in organo-metallic emitting complexes. The detailed understanding of these processes leads us to design with our partners new materials with enhanced emission characteristics and stability.
