Shape Evolution of Single-Crystalline Iron Oxide Nanocrystals

摘要

The design and synthesis of architectural nanocrystals have been among the important research topics of nanoscience due to their unique size and shape-dependent phenomena. Therefore, systematic directions for synthetic methods and an understanding of the mechanisms by which the size and shape of the nanocrystals can be controlled are of particular interest. Recent demonstration of a variety of novel shapes such as rods (CdSe), branched rods (CdS, CdTe, MnS), stars (PbS), and tetrahedrons (Pt, CdS) developed by us and others suggest that the role of capping ligand plays a critical role in the shape-control processes.
