Nanocrystals of the I-III-VI2 semiconductors are of potential interest for solar-energy applications, due to their high absorption coefficient in the red to near-infrared region. In this study, CuInS2 nanoplatelets are prepared from a variety of precursors in primary-amine solvents.  The platelets exhibit both rectangular and hexagonal morphologies, and have lateral dimensions in the range of 20 � 30 nm.  XRD analyses establish the wurtzite rather than the (bulk) chalcopyrite crystal structure for the nanoplatelets.  The characterization and spectroscopic properties of these nanoplatelets will be presented.
