Dynamic Sulfur Reservoir Programs Cation-Exchange Kinetics in PbS Quantum Dots for Short-Wave Infrared Imaging Chips

Abstract Cation-exchange synthesis produces monodisperse PbS quantum dots (QDs), yet its central limitation─precursor preparation and dropwise injection─is usually treated as a practical issue. Here, we recast it as sulfur chemical-potential programming; that is, ethyl ziram (EZ)...
