Large‐Scale Programmable Synthesis of PbS Quantum Dots
Abstract
The most common method of synthesizing colloidal quantum dots (QDs) relies on an increasing particle size through increasing reaction time. We demonstrate a synthesis where the QD size is programmable through the use of a secondary phosphine sulfide precursor. The reaction runs to thermodynamic completion, resulting in a desired PbS diameter for a given set of specific reaction conditions, with no need for reaction quenching or post‐synthesis size‐separation. Moreover, this method is shown to produce high‐quality PbS QDs on the grams scale.
