Semiconductor Nanocrystals: Science and Applications — •Moungi Bawendi — Department of Chemistry, Massachusetts Institute of Technology, 77 Massachusetts Ave., Cambridge, MA 02139, USA

Semiconductor nanocrystal quantum dots that are of high crystal quality and have high fluorescence quantum yields have spurred detailed studies of their electronic and optical properties. Their color range with size as a result of quantum confinement has motivated applications in fields ranging from biology to optical devices. This talk will review the chemistry of nanocrystal quantum dots, the study of the fluorescence properties of single nanocrystal dots and the insights that have been obtained, the incorporation of nanocrystal dots in organic light emitting devices, the observation of stimulated emission and lasing from nanocrystal dots under optical pumping and the application of nanocrystal dots in biological and biomedical imaging.
