Self‐organization of size‐selected, nanoparticles into three‐dimensional superlattices

Abstract

Three‐dimensional quantum dot superlattices with fcc structure have been formed using reverse micelles and self‐organization of Ag 2 S 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.
