Stimuli-Responsive Nanostructured Optical Materials

Nanostructured materials with optical properties responsive to external stimuli are gaining increasing interests due to their intrigue potential applications in printing, sensing, signage, security documents, displays, and other color related devices. In this presentation, I will discuss our recent progresses on the development of chemical approaches for the fabrication of various nanostructured materials, whose optical properties can be dynamically tuned by controlling the spatial arrangement of the nanoscale building blocks. I will further demonstrate that many novel optical materials could be developed by manipulating the diffraction, refraction, birefringence, and electronic resonances, such as surface plasmon through controlling the interaction between light and the nanostructures of dielectric and metallic materials.

About the Speaker

Professor Yadong Yin received his B.S. (1996) and M.S. (1998) in Chemistry from the University of Science and Technology of China, and Ph.D. (2002) from University of Washington, Seattle with Professor Younan Xia. He was a postdoctoral fellow at the University of California, Berkeley (2003-2005) with Profesor A. Paul Alivisatos. Soon he joined the Molecular Foundry at the Lawrence Berkeley National Laboratory. After being a staff scientist at LBNL for a year, he joined the faculty at the Department of Chemistry, University of California, Riverside in 2006. His research interest focuses on the synthesis, self-assembly, and functionalization of nanostructured materials for catalytic, analytical, and photonic applications. His recent recognitions include Cottrell Scholar Award (2009), DuPont Young Professor Grant (2010), 3M Nontenured Faculty Grant (2010), and NSF CAREER award (2010). He is currently an associate editor of the Journal of Materials Chemistry C.
