Nanocrystals of binary metal tellurides, such as PbTe, Ni 2Te3, and Cu7Te5, are synthesized by the polyol method under microwave radiation and studied using X-ray powder diffraction, transmission electron microscopy, high-resolution transmission electron microscopy, and photoacoustic spectroscopy. Binary tellurides are formed only in the case when ethylene glycol is used as a reducing agent and only when the reaction is carried out under microwave radiation. No product is formed when the reactions are performed using a conventional technique of heating. The synthesis of the aforementioned metal tellurides is described, and the proposed mechanism of the reaction is discussed.
