Unveiling Formation Pathways of Ternary I-III-VI CuInS₂ Quantum Dots and Their Effect on Photoelectrochemical Hydrogen Generation.

ABSTRACT: Understanding the formation mechanisms of semiconductor nanocrystal quantum dots (QDs) is essential for fine-tuning their optical and electrical properties. Despite their potential in solar energy conversion, the synthesis processes and resulting properties of ternary I-III-VI QDs remain underexplored due to the complex interplay among their constituent elements. Herein, the formation mechanism of ternary I-III-VI CuInS₂ QDs is investigated, and a direct correlation between their synthesis pathways and photoelectrochemical hydrogen generation performance is established. Two distinct formation pathways governed by the Lewis acid strength of the precursors are revealed. Precursors with weaker Lewis acid strength, such as indium acetate-alkylamine complexes, induce the nucleation o
