The research group is deeply rooted in the realm of novel optoelectronic materials and devices, with a primary focus on unraveling the intricate physical mechanisms behind printed display optoelectronic materials and devices. Our mission extends to the realization of highly stable and cost-effective thin-film light-emitting display devices. We delve into the optoelectronic properties of devices, investigating fundamental scientific issues such as charge transport and recombination, trap effects and defect nature, as well as material and device lifetime and stability mechanisms. We have established long-term cooperative exchanges with institutions such as the Max Planck Institute for Polymer Research, Stanford University, and Kyushu University. We maintain close connections with industry leaders such as Apple Inc. and Huawei Technologies' European Research Institute, and have established project collaboration relationships with companies like Guangdong Juhua Corporation, Tongji University, and Zhejiang University.
