In this paper, we report a simple and clean method of producing nanocrystalline silver tellurides in organic solvent systems by high-intensity ultrasonic irradiation at room temperature. Ag 2 Te and Ag 7 Te 4 are prepared in an ethylenediamine system and an ethanol system, respectively. The products
Nanocrystalline Cu 7 Te 4 was directly synthesized by the reaction of CuCl 2 ' 2H 2 O and tellurium in an autoclave with ethylenediamine as solvent at 1603C for 10 h. X-ray powder di4raction patterns, X-ray photoelectron spectra, and transmission electron microscope images show that the products are
Te 10 have been synthesized at 1123 K with the use of reactive 6uxes of alkali-metal halides ACl (A โซุโฌ K, Rb, Cs). All crystallographic data were collected at 153 K. These compounds crystallize in space group Pnnm of the orthorhombic system with two formula units in cells of dimensions (A 3
