Coreduction colloidal synthesis of III-V nanocrystals: the case of InP

Abstract

(Figure Presented) Finding the little InP particles: A core-duction method allows high-quality colloidal InP nanocrystals to be synthesized by using PCl3 as the phosphorus source and superhydride as the reducing agent. Etching the as-grown nanocrystals with HF leads to high-efficiency photoluminescence. The synthetic strategy can be extended to the preparation of other III-V nanocrystals with the corresponding pnicogen halides. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
