I've read that usually capping ligands help stabilize the NC's and mediate their growth, I was just curious to the ranges in size and geometries/crystallography of any NC grown without any of these ligands present. Does anyone know of a study?
Dear David,
Gas phase nanoparticle synthesis using a sputtering technique does not require any ligand chemicals as well as the related solvents/medium. Yet, you can create or grow desirable nanoparticles in a controlled manner, I.e. Size, shape, and composition.
best,
Several techniques can be used to prepare nanomaterials from pure metal and salts as precursors without the need of ligand. Heating-evaporation, electrodeposition, milling, precipitation are some of the methods used. However, according to the literature, there is a serious challenge concerning the control of shape, size and even composition. This is pronounced when the method aims to reduce the size of nanomaterials in all three dimensions.
