GB/T 24370-2021 "Nanotechnology—Characterization of cadmium chalcogenide colloidal quantum dots—UV-Vis absorption spectroscopy" specifies the method for characterizing cadmium chalcogenide colloidal quantum dots using ultraviolet-visible absorption spectroscopy, and is applicable to the performance testing of relevant nanomaterials. The test requires a UV-Vis spectrophotometer with an appropriate wavelength range, adequate resolution, and stable baseline, used in conjunction with standard cuvettes. By preparing uniformly dispersed quantum dot samples, measuring their absorption spectra, and analyzing parameters such as the position of characteristic absorption peaks and full width at half maximum, this standard provides a technical basis for the size control and performance evaluation of quantum dots.
