Abstract A new controlled aging methodology was developed for the synthesis of PbS colloidal quantum dots (QDs), applying larger PbS QDs as a starting material for smaller QDs by application of environmentally friendly oleic acid and oleylamine as reagents. This simple and mild procedure provides a possible strategy for tailoring the size-dependent properties of PbS QDs.

PbS 胶体量子点在温和条件下的受控老化

摘要 开发了一种新的受控老化方法来合成 PbS 胶体量子点 (QDs)，通过应用环境友好的油酸和油胺作为试剂，将较大的 PbS QDs 作为起始材料用于较小的 QDs。这种简单而温和的程序为定制 PbS QD 的尺寸相关特性提供了一种可能的策略。
