SAXS on colloidal quantum dots

In this data sheet it is demonstrated that SAXS measurements performed on PANalytical’s multipurpose XRD platforms allow to easily determine particle size distributions and specific surface areas of colloidal quantum dots and to probe for the presence of aggregates.

SAXS measurements on dilute dispersions of CdS quantum dots in toluene were performed on the Empyrean multipurpose XRD platform. A good data quality could be obtained, which allowed a consistent data analysis with the EasySAXS software to determine the size distribution and the specific surface area of the nanoparticles.
