Abstract :
A convenient hydrothermal method has been successfully developed to prepare nanocrystalline CuSe and Ag2Se, based on the reactions of CuCl2·2H2O and AgNO3 with elemental selenium in dilute aqueous ammonia systems, respectively. X-ray diffraction (XRD), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS) examinations were carried out to determine the phase, grain size, morphology, and purity of the products. The aqueous ammonia system plays an important role in the formation of nanocrystalline CuSe and Ag2Se. A possible mechanism is proposed.
