Ag2Se, CuSe and PbSe were prepared by irradiating the mixtures of AgNO3, CuI or PbCl2 with selenium in ethylenediamine (en) with ultrasound at 18 kHz, using a commercial ultrasonic cleaner, respectively. X-ray powder diffraction (XRD) patterns and transmission electron microscope (TEM) images show that the products are orthorhombic Ag2Se, hexagonal CuSe and cubic PbSe, respectively, and all are well crystallized in nanometers.
