The synthesis of III-V quantum dots has been long known to be more challenging than the synthesis of other types of inorganic quantum dots. This is attributed to highly reactive group-V precursors. We synthesized molecules that are suitable for use as group-V precursors and characterized their reactivity using multiple complementary techniques. We show that the size distribution of indium arsenide quantum dots indeed improves with decreased precursor reactivity.
III-V 量子点的合成一直以来都比其他类型的无机量子点更具挑战性。这归因于高度反应性的 V 族前体。我们合成了适合用作 V 族前体的分子，并使用多种互补技术对其反应性进行了表征。我们表明，随着前体反应性的降低，砷化铟量子点的粒径分布确实得到了改善。
