Sonochemical synthesis of size-controlled mercury selenide nanoparticles

A novel sonochemical method for preparation of mercury selenide has been developed based on the reaction of mercury acetate and sodium selenosulfate in an aqueous system at room temperature. Different complexing agents were used to control the particle size. X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS) were used to determine the phase, purity, size and morphology of the products. The results showed that the HgSe nanoparticles with different sizes could be obtained in the presence of complexing agents.
