Professor Jin Zhang received his PhD from Peking University and Lanzhou University in 1997. After a two year postdoctoral fellowship at the University of Leeds, UK, he returned to Peking University where he was appointed Associate Professor (2000) and promoted to Full Professor in 2006. In 2013, he was appointed as Changjiang professor. His research focuses on the controlled synthesis and spectroscopic characterization of carbon nanomaterials. Dr. Zhang has received the National Science Foundation of China for Distinguished Young Scholars in 2007 and 2nd grade of the State Natural Science Award in 2008 (2nd contributor). Dr. Zhang has published over 160 peer-reviewed journal articles. And he now is the editor of Carbon.

Lighting up the Raman Signal of Molecules in the Vicinity of Graphene Related Materials

Surface enhanced Raman scattering (SERS) is a popular technique to detect the molecules with high selectivity and sensitivity. Nevertheless, how to make the SERS signals repeatable and quantitative, and how to understand the chemical enhancement mechanism are still big challenges. Recently, graphene, as well as the other two dimensional (2D) materials, were developed to be used as a Raman enhancement substrate, which can light up the Raman signals of molecules, and these substrates were demonstrated to be a promising for micro/trace species detection. In this talk, the multi-role of graphene and its realted materials played in SERS is overviewed in turn, including a Raman probe, a substrate, an additive and a building block of a flat surface for SERS.
