Abstract: Nanoscience is recognized as one of the most exciting frontiers in modern science. The excitement stems from the impact nanoscience is having in both basic science and technology development. This seminar will discuss the fundamental principles behind the synthesis of high-quality nanocrystals. Based on these principles, we have synthesized semiconductor nanocrystals with dopants at controlled radial positions. In addition, we show that these principles can be used to control nanocrystal assembly through a supramolecular synthesis, which have resulted in a new class of well-defined colloidal superparticles (i.e., supercrystalline collection of artificial atoms in the form of colloidal particle). The ability to control nanocrystal synthesis and assembly would open a rational way to fabricate functional materials of interest for applications such as biomedical diagnosis, catalysis, plasmonics, and solar voltage cells.
