CURRENT RESEARCH
My work in the group is currently concerned with Organic Light Emitting
Devices (OLED's) made from both small organic molecules and polymers.
We are searching for materials that exhibit a brightness on the order of
10,000 Candelas per square meter, have long device lifetimes, and are
mechanically robust. The electroluminescence (EL) of the device is
generally based on the light emission from the recombination of
electron-hole pairs (excitons) in the singlet state. Dopants
containing metal complexes allow triplet state excitons to spin flip and thus
recombine radiatively, increasing the device EL. Work is being done to
find efficient emitters using these organic metal complexes. Because of
there pliable nature, the polymeric materials immediately invite the
possibility of flexible displays for mobile phones, PDA's, laptops, etc.
Light emitting devices made from organic and polymeric materials will
certainly provide wonderful applications in optical electronics.
