摘要：

In this paper we show that self-organization of colloidal PbSe and CdSe semiconductor nanocrystals with a size ratio of 0.57 leads to binary structures with a AB(2) or a cuboctahedral AB(13) lattice. The type of superlattice formed can be regulated by the relative concentration of both nanocrystals in the suspension.
