Abstract

This paper is an overview of research in my group over the past 10 to 15 years. Our work has explored the synthesis, assembly, nanostructure characterization, and optical properties of a wide variety of semiconductor quantum dots in II-VI, III-V, and other systems. Our early work was aimed at applications in photonics and fiber optics but more recently we have worked on biomolecular engineering with quantum dots for immunoassays and related interests. The chosen hosts for the quantum dots are glasses, polymers and sol-gel prepared xerogels. The synthesized quantum dot nanocomposites have been most commonly characterized by X-ray diffraction (XRD), atomic force microscopy (AFM), and high resolution transmission electron microscopy (HRTEM). Absorption and photoluminescence (PL) spectroscopy data are also reported on selected quantum dot samples. A short summary of ongoing research in our laboratory on magnetic iron oxide nanocrystals for biological applications is also presented.
