Abstract

The surface morphology is one of the important factors to determine the optical properties of colloidal quantum dots. Colloidal CdSe dots were synthesized by the injection of precursor molecules in a hot surfactant, and a series of samples were obtained by partially replacing the ligands on the surface of these dots with 2-mercaptoethanol. 2-mercaptoethanol results in the decrease of the photoluminescent quantum yield, and the time-resolved photoluminescent (PL) spectra are significantly modified. The effect of the surface morphology is discussed.
