Research Interests

Our research interests cover a broad range of cutting-edge materials science projects. One of our major interests has always been to thoroughly characterize optical materials (single crystals, ceramics, nanocrystals, glasses, polymers) doped with rare earth (RE) and transition metal ions, and finally, evaluate their potential for various photonic applications, including lasers. As the nanotechnology field is fast emerging and its applications are expected to be limitless. Therefore, we are currently involved in the syntheses, characterization and modeling of various nanoparticles of RE ions doped in multitude of hosts, noble metals (Au and Ag), and their conjugates. Our goals are to understand the fundamental physics of these nanoparticles, their optical and magnetic properties, their structural effects, such as size, surfaces, interfaces, etc., on their optical properties, and ultimately, their major photonic and biomedical applications such as lasers, optical fibers, planar waveguides, security authentication, pigments, fluorescence labeling, scintillators, lighting, bio-imaging, bio-sensors, cancer therapy, optical displays, optical memories, to name just a few.
