Semiconductor nanocrystals, also known as quantum dots, have unique optical and electronic properties depending on their size and shape. Synthesis of heterostructured semiconductor nanocrystals enables various control of particle properties by introducing new composition and geometries. In this study, we introduced cation exchange method to synthesize heterostructured nanocrystals. Based on the understanding of binding energy between cations and organic ligands, Cd-to-Zn direct cation exchange reaction is successfully induced in CdSe quantum dots. We also expanded our study on two-dimensional colloidal nanoplatelets and synthesized new type of heterostructure. |
