Abstract
Herein, we investigate a synthetic approach to prepare copper indium sulfide nanocrystals at room temperature.
Highlights
Metal chalcogenide nanocrystals and nanomaterials have attracted a lot of attention during the last decade because of their interesting optical and electrical properties due to quantum con nement effects based on variations in size and shape and due to chemical tuning of the chemical composition and the ligand environment
We investigate the synthesis of CuInS2 nanocrystals from the direct reaction of oleylamine with a mixture of copper and indium xanthates in solution at room temperature
By replacing hexylamine with the long-chained oleylamine, which is a common capping ligand for metal sul de nanoparticles,[20] oleylamine controls the growth and stabilizes the formed copper indium sul de, which leads to a de ned growth of CuInS2 nanocrystals
