Abstract
In this paper, we report a simple and clean method of producing nanocrystalline copper tellurides in an organic solvent system by high-intensity ultrasonic irradiation at room temperature. Cu4Te3 is prepared in a pure ethylenediamine system and Cu7Te4 is prepared in ethylenediamine with hydrazine hydrate. The products are characterized by X-ray powder diffraction (XRD), transmission electron microscope (TEM), and X-ray photoelectron spectra (XPS). Ultrasonic irradiation and the solvents are both important in the formation of products. The formation mechanism of the nanocrystalline tellurides under high-intensity ultrasonic irradiation is also discussed.
