Abstract: (1691 Views)
Dynamic light scattering is one of the most commonly used methods for determining the size distribution of nanoparticles in liquids. In this method, the particle diameter is calculated by monitoring the time fluctuations in the intensity of the scattered light from the nanoparticles. In this paper, the experimental setup of the dynamic light scattering method using a 532 nm laser and a PMT detector has been installed and the practical results of this setup for samples of silver nanoparticles are presented. The size distribution histogram obtained from this experiment has been compared with the results of a standard laboratory device, which indicates an excellent match.
Keywords: Dynamic light scattering, the size distribution histogram, the size distribution of nanoparticles
