Low-temperature synthesis of CuS nanorods by simple wet chemical method

CuS nanorods of length 60-100 nm and 15 nm in diameter have been synthesized by simple wet chemical method at 105 degrees C using CuCl2 center dot 2H(2)O as Cu-precursor, CS2 as S-source and ethylenediamine as the attacking reagent. The plausible reaction mechanism has been proposed and the effect of reaction temperature on morphology has been discussed. X-ray diffraction (XRD) pattern suggests the formation of hexagonal phase CuS. The morphology of the products has been studied by transmission electron microscope (TEM) analysis. A detailed optical study has also been done. (c) 2006 Elsevier B.V. All rights reserved.
