摘　　要：Progress has been made in accurately manipulating the size and shape of monodisperse nanocrystals over past 30 years.In 1993,Bawendi et al.synthesized monodisperse CdS,CdSe and CdTe nanocrystals with similar size by a hot-injec-tion method[1].After two years,they prepared CdSe nanocrys-tal superlattices by self-assembling method with two distinct morphologies:faceted colloidal crystals and ordered thin films.The size and spacing of nanocrystals were controlled with a nearly atomic precision[2].Then,engineering morpho-logy,interaction and surrounding environment are encour-aged to construct superlattices at atomic scale.Meanwhile,the advanced technologies like electron microscopy and X-ray related tools help scientists to deeply understand the struc-tures and properties of nanocrystal superlattices[3].Com-pared to individual nanocrystal,their superlattices indicate col-lective properties due to coupling between nanocrystals[4].For instance,their original properties are enhanced because the ordered nanocrystals interact with each other under the light,electric or magnetic field;new properties can be gener-ated by the periodically ordered structures of the assembly;and comprehensive properties can be obtained via assem-bling nanocrystals with different functions.
