Abstract
[Image: see text] This paper examines the molecular mechanism of InP colloidal quantum dot (QD) syntheses. Unlike methods for monodisperse PbSe and CdSe we found that existing InP syntheses result in total depletion of molecular phosphorous species following nucleation, so QD growth is due exclusively to non-molecular ripening. We find that amines inhibit precursor depletion via solvation, and these findings may lead to better synthetic methodology for InP QDs.
摘要
本文研究了 InP 胶体量子点 (QD) 合成的分子机制。与单分散 PbSe 和 CdSe 的合成方法不同，我们发现现有的 InP 合成方法会导致成核后分子磷物种完全耗尽，因此 QD 生长完全是由于非分子的熟化。我们发现胺通过溶剂化抑制前体的消耗，这些发现可能为 InP QD 的更好的合成方法奠定基础。
