英文摘要	A simple approach to control the self-assembly of zns nanocrystals into well-defined, uniform, three-dimensional, micrometer-scale, solid ellipsoidal structures with rattle-type, multishelled, and hollow architectures is presented. there is no surfactant or small molecule to assist the self-assembly of the nanocrystals. a possible mechanism of the controlled self-assembly is proposed. the growth process can be divided into two stages: 1) the formation of ellipsoidal architectures via oriented aggregation, the growth kinetics of which is primarily attributed to the charge-charge, charge-dipole, and dipole-dipole interactions of preformed zns nanocrystals; and 2) ostwald ripening, which results in multishelled, rattle-type, and hollow structures. this self-assembly concept is also applicable to other metal sulfides.
