Abstract
Nanocrystalline Cu7Te4 was directly synthesized by the reaction of CuCl2. 2 H(2)O and tellurium in an autoclave with ethylenediamine as solvent at 160 degrees C for 10 h. X-ray powder diffraction patterns, X-ray photoelectron spectra, and transmission electron microscope images show that the products are hexagonal Cu7Te4 phase and well crystallized with an average size of a bout 15 nm. The solvent ethylenediamine played an important role in the syn thesis of nanocrystalline Cu7Te4. The reaction mechanism was proposed. (C) 1999 Academic Press.
