Ion Exchange Synthesis of III-V Nanocrystals

摘要

Ⅲ-Ⅴ nanocrystals displaying high crystal-linity and low size dispersity are difficult to access by direct synthesis from molecular precursors. Here, we demonstrate that cation exchange of cadmium pnictide nanocrystals with group 13 ions yields monodisperse, crystalline Ⅲ-Ⅴ nanocrystals, including GaAs, InAs, GaP, and InP. This report highlights the versatility of cation exchange for accessing nanocrystals with covalent lattices.
