Sonochemical Synthesis of CdSe Hollow Spherical Assemblies Via an In-Situ Template Route

Authors


Abstract

CdSe hollow spherical assemblies composed of 5 nm nanoparticles have been synthesized sonochemically. During the process, amorphous Cd(OH)2, which acts as the in-situ template, directs the growth of primary CdSe nanoparticles on its surface and their assembly into hollow spherical structures. The Figure is a schematic of the proposed mechanism for the formation of the hollow chalcogenide spheres.
