Preparation and Characterization ot CdSe QDs

摘要

An optimized synthesis route of CdSe quantum dots (QDs) in an aqueous solution was obtained. The shape, crystal structure and optical property of CdSe QDs were also characterized by XRD, UV-Vis and TEM. The result showed that the high-quality cubic CdSe QDs with 3 nm was obtained. The mechanisms about the influence factors were also presented.
