Research Profile

     Dong Zhenchao,BSc (1983) from Sichuan University,  MSc (1987) from Xiamen University, Ph.D. (1990) in Physical Chemistry from Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences (CAS).
     In 1992, Dong did his post-doctoral research at Iowa State University (Ames Laboratory), USA. In 1996, Dong went to work at the National Institute for Materials Science (NIMS), Japan, where he had been appointed as Senior Researcher and Subtheme Leader. Since 2004, he has been working as a full professor at University of Science and Technology of China (USTC). Dong is a recipient of New Century Talents Supporting Program” (Ministry of Education) and "Hundred Talent Project" (CAS).
     Dong's research focuses on nanotechnology and single molecule optoelectronics, exploring scientific frontiers related to solid naked cluster chemistry, single molecule electroluminescence, and molecular plasmonics. In early days, through a balanced tuning of size factor and electronic “magic number”, Dong designed and synthesized a series of unprecedented naked clusters such as the thallium icosahedral cluster, which extended the Zintl concept and the solid “naked” cluster chemistry. In recent decade, he has been engaged in research on the control of photonic states at the molecular scale, single-molecule electroluminescence, and nanoplasmonics, and has established a unique combined technique of high-resolution scanning tunneling microscopy and high-sensitivity single-photon detection. Using the highly localized excitation of tunneling electrons, Dong aims to explore the optoelectronic behavior of a single molecule in a nano-environment from the space, energy, and time domains. Through tuning of photonic states in molecular tunnel junctions, Dong detected for the first time the molecular fluorescence resulting from HOMO-LUMO transitions at the molecular scale, and discovered striking molecular electroluminescence phenomena: the relaxationless hot fluorescence, “energy forbidden” upconversion electroluminescence, and“colored” spectral tuning.
     Dong is currently the PI of a number of research projects supported by the Ministry of Science and Technology, the Chinese Academy of Sciences, and the National Natural Science Foundation of China. He has published more than 120 papers indexed by SCI and participated in the writing of four monographs. He has presented many invited talks at both domestic and international conferences, including those organized by the American Chemical Society and the International Vacuum Congress. He is the first author of six papers published in Nature Photonics, Phys. Rev. Lett., J. Am. Chem. Soc., and Angew. Chem., with a total of citations exceeding one thousand times (h-factor=21). He is now serving as a deputy secretary general of the Chinese Vacuum Society. In 2010, Dong was honored as “National Outstanding Science and Technology Workers” awarded by the China Association for Science and Technology.
