Early Stages of ZnS Nanoparticle Growth Studied by In‐Situ Stopped‐Flow UV Absorption Spectroscopy

Abstract

Abstract The early stages of ZnS nanoparticle growth from supersaturated solution are investigated in situ by stopped‐flow UV absorption spectroscopy with a time resolution of 1.28 ms. A model for data analysis is suggested which makes it possible to study both the average particle radius and the concentration. The average radii lie in the sub‐nanometer range. During the first 40 ms, growth is predominantly governed by ripening.
