Research

Our research interests focus on the discovery and understanding of functional solid-state materials and nanomaterials employed in optical energy conversion technologies such as biosensing, lighting, and materials manufacturing. Our goals are to synthesize new classes of functional materials and nanomaterials, to understand compositional control of structure-luminescence relationships, and to enlarge the toolkit of synthetic and spectroscopic techniques that enable such understanding.

We seek to achieve precise control over the stoichiometry, morphology, structure, and functionality of the materials we synthesize. Synthetic approaches employed in our group include, but are not restricted to, colloidal synthesis, solvothermal synthesis, thermal evaporation, and high-temperature solid state reactions. Once in hand, these materials are characterized using multiple and complementary analytical techniques to achieve a comprehensive description of composition-structure-function relationships. This information is critical to develop materials by design as it enables understanding of the effect of chemical composition on the behavior of functional chemical units. Characterization techniques include elemental analysis (ICP), thermogravimetric and calorimetric analysis (TGA/DSC), powder X-ray diffraction (Rietveld analysis), X-ray total scattering (pair distribution function analysis), X-ray absorption (XANES/EXAFS), electron microscopy (SEM/TEM), vibrational spectroscopy (Raman/IR), and UV-vis diffuse reflectance, and fluorescence spectroscopy (steady-state and time-resolved). Structural studies are an integral part of our research and systematically guide synthetic efforts.
