Lian Duan
Lian Duan received his B.Sc. from the Department of Chemistry, Tsinghua University, China in 1998 and his Ph.D from the Department of Chemistry, Tsinghua University, in 2003. He is now with the Department of Chemistry, Tsinghua University. His research interests focus on organic light‐emitting materials and devices. He proposed a new excitonic strategy to harvest triplet excitons by using materials with thermally activated delayed fluorescence as hosts for conventional fluorescent or phosphorescent dopants, leading to ideal OLEDs with low voltage, high efficiency, long lifetime and low efficiency roll‐off.
