Use of UV-Vis absorption spectroscopy in the characterization of cadmium chalcogenide colloidal quantum dots1 Scope This Technical Specification provides guidelines for estimating the diameter and the number concentration of monodisperse cadmium chalcogenide (CdTe, CdSe, CdS) quantum dots (QDs) with a narrow size distribution in a colloidal dispersion using Ultraviolet visible (UV Vis) absorption spectroscopy. The analysis of the spheroidal particle size is applicable to the diameter range of 3,5 nm to 9 nm for CdTe, 1 nm to 8 nm for CdSe, and 1 nm to 5,5
