Our research activities include the synthesis, characterization, and applications of nano/microstructured materials comprising luminescent lanthanide and transition metal ions. We develop chemical methods for synthesizing new nanocrystals, microcrystals, and nanocomposites. Extensive characterizations of the nanoparticles are carried out with microscopy and spectroscopy techniques. For doped nanoparticles, the control of dopant concentration and distribution (spatial confinement) are of particular interest. Our research goal is to rationally assemble atoms/ions at the nanometer length scale towards ''Lab on a Particle'' architectures for better understanding and control of ionic interactions. By taking advantage of the shape, chemical composition, and structural complexity and anisotropy, one can fine tune the properties of the materials to meet specific needs in technological applications.
