摘要：

Ag2Se nanocrystals were rapidly synthesized by the sonochemical reaction between Ag ions and Se powders in diluted ammonia water. By using different complexing agents (NH3, citric acid or KSCN) in the reaction system, Ag2Se nano-spheres with different sizes were obtained. X-ray diffraction patterns showed that the samples obtained was orthorhombic beta-Ag2Se. The morphology was characterized by scanning electron microscopy (SEM). This mild method may be extended to prepare other chalcogenides nanocrystalline at room temperature. (c) 2006 Elsevier B.V. All rights reserved.
