摘要The growth mechanism of glutathione (GSH) capped ZnSe quantum dots (QDs) obtained from the aqueous synthesis method is studied by in situ X-ray absorption fine structure (XAFS) utilizing a flow reactor and synchrotron radiation. Detailed analysis of the Se K-edge EXAFS data reveals that the growth of ZnSe QDs from aqueous synthesis undergoes a fast nucleation process and then a slow growth stage, which follows the two-stage growth mechanism. The ZnSe QDs are strained to minimize the total free energy, and the contraction of Se-Zn bond relaxes with time. This shows the promising capability of in situ XAFS to investigate the growth process of nano-materials synthesized by chemical solution method. (C) 2010 Elsevier B.V. All rights reserved.
