人们早就知道,合成III-V量子点比合成其他类型的无机量子点更具挑战性。这归因于高活性的V族前体。我们合成了适合用作V族前体的分子,并用多种互补技术表征了它们的反应活性。我们发现,随着前驱体反应性的降低,砷化铟量子点的尺寸分布确实得到了改善。
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.
