Improved Precursor Chemistry for the Synthesis of Ⅲ-Ⅴ Quantum Dots

摘要

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.
