Abstract

Ternary chalcogenide semiconductor type CuInS2 nanocrystals were prepared by solvothermal procedures, using CuCl, In and S as precursors in distilled water and ethylenediamine as solvents. The precipitates were characterized by XRD and TEM. Although CuInS2 chalcopyrite phase has been obtained in both solvents, as it is demonstrated by the XRD spectra, the TEM images reveal great differences in the morphology of the nanocrystals. In water nanoparticles of 5-20 nm mean diameter are obtained, instead 10-100 nm wide and 1-2 micron long nanorods and nanofibers resulted in ethylenediamine. A possible mechanism of asymmetrical growth is discussed.
