Novel Approach to the Preparation of Lead Chalcogenide Colloidal Quantum Dots and Properties Thereof
In this work, we report the study of resizing of lead chalcogenide quantum dots, both PbS and PbSe, in the presence of the oleylamine/oleic acid mixture. We demonstrate that the resizing of lead chalcogenide nanocrystals could be performed in aprotic non-polar solvents. The kinetics of the shrinking...

| description | In this work, we report the study of resizing of lead chalcogenide quantum dots, both PbS and PbSe, in the presence of the oleylamine/oleic acid mixture. We demonstrate that the resizing of lead chalcogenide nanocrystals could be performed in aprotic non-polar solvents. The kinetics of the shrinking could be followed by the measurement of absorption at 400 nm. The amount of a resizing reagent, namely the oleylamine/oleic acid mixture, influences the rate of reaction. This procedure could serve for the preparation of smaller lead chalcogenide quantum dots from a larger one. |
