报告简介：
Elaborate chemical synthesis methods allow the production of various types of inorganic nanocrystals (NCs) with uniform shape and size distributions. Then, how can we synthesize NCs with thermodynamically metastable phases or very complex structures? The transformation of already-synthesized NCs via elemental substitutions, such as ion exchange reactions for ionic NCs [1-3] and galvanic replacement reactions for metal NCs [4], can overcome the difficulties facing conventional one-step syntheses. In particular, NC ion exchange reactions have been studied with numerous combinations of foreign ions and ionic NCs with various shapes. The functionality of the resulting ionic NCs, including semiconducting and plasmonic properties, can be easily tuned in a wide range, from the visible to near-infrared [5,6]. Here we focus on the ion exchange reactions of ionic NCs from sub-nm to µm range, highlighting important aspects such as the preservation of appearance and dimensions [7-11]. Finally, the formation of unprecedented Z3-type FePd3 NCs by substituting a small amount of Pd with In is discussed on the basis of interelement miscibility among Fe, Pd, and In [12,13].
