Abstract

Three-dimensional quantum dot superlattices with fcc structure have been formed using reverse micelles and self-organization of Ag2S nanocrystals. It is reported that the size distribution of the nanoparticles can be narrowed by a chemical treatment of the interface and by particle extraction from the micelles. The formation of well-defined tow- or three-dimensional ordered arrays is required for the development of new types of optical gratings, optical filters, antireflective surface coatings, data storage systems, and microelectronics.
