Scope

This document presents a method for evaluating the diameter and particle concentration of monodisperse cadmium chalcogenide (CdTe, CdSe, and CdS) colloidal quantum dots using ultraviolet-visible (UV-Vi s) absorption spectroscopy. This document is applicable to the analysis of CdTe with a diameter of 3.5nm~9nm, CdSe with a diameter of 1nm~8nm and CdS monodisperse spherical quantum dots with a diameter of 1nm~5.5nm.
