Tuning the Synthesis of Ternary Lead Chalcogenide Quantum Dots by Balancing Precursor Reactivity

We report the synthesis and characterization of composition-tunable ternary lead chalcogenide alloys PbSe x Te1-x , PbS x Te1-x , and PbS x Se1-x . This work explores the relative reaction rates of chalcogenide precursors to produce alloyed quantum dots (QDs), and we find the highly reactive bis(tri...
