研究领域
Our research efforts primarily focus on electrochemistry and single molecule spectroscopy. We are interested in in-situ spectroscopic studies of adsorption at electrode and electrocatalysis, and electrogenerated chemiluminescence by combining electrochemistry and spectroscopy with high time and spatial resolution. Our current research projects include
preparation of well-defined functional nanostructures, including metallic nanocrystals with synergistic functions, inorganic/conjugated polymer and small organic molecule semiconductor nanostructures, and investigation of their electrochemical and optical properties, such as photoelectrochemistry, electrogenerated chemiluminescence and catalytic behavior for fuel oxidation and water splitting with solar energy
using well-defined functional materials to fabricate devices such as efficient solar cells, memory, light-emitting diodes, waveguides and smart sensors for ultrasensitive detection of biomolecular recognition events
using single molecule electrochemical methods to understand structure-function relationships of nanostructures at single molecule/particle level
Finally, we are interested in making plasmonic devices using electrochemical methods that can be operated below the optical diffraction limit for next-generation optoelectronics.
Students involved in these highly interdisciplinary projects will interact with scientists in various research areas from optics and electrochemistry to material science at the University of Alabama and other institutions across the country. Students will receive excellent training in various kinds of nanofabrication and surface characterization tools in addition to learning advanced electrochemistry and single molecule spectroscopy. The Department of Chemistry of the University of Alabama provides students with an advanced research environment, where Ph.D. students will be exposed to a broad range of scientific perspectives.
