Dr. Townsend's research group focuses on applied nanomaterials for printed electronics and functional fluorescent metal coatings. Research students are exposed to synthesis of inorganic nanocrystals that can be made small enough to be dispersed in solvents for ink-jet printing. By layering nanomaterials, electronic devices such as photovoltaics and LEDs can be fabricated and tested and characterized.
Additionally, we investigate electrochemical deposition of metal composite films with unique properties. By incorporating foreign particles into a metal film, the materials properties such as hardness, durability, fluorescence, can be tuned. Students working on electrochemistry projects are exposed to electrochemistry, metal plating and redox reactions.
