Dynamic light scatting (DLS) technique is an effective method of nano and submicron particle size measurement. In this paper, a experiment method to measure quantum dots based on DLS was built with the analysis of the quantum dots and dynamic light scattering system. Experimental device is established to finish the test and analysis by contin algorithm from correlation curve.The data form was c inversion of the experimental data, the size of quantum dots was got ompared with that from election microscope and particle size formula. The results show that the dynamic light scattering is an effective method for measuring the particle size of quantum dots and provide a new and fast means of the analysis of the optical properties of quantum dots.
