Dynamic light scattering is one of the most popular methods for determining particle size. With a light beam like a laser beam on a solution consisting of spherical particles in Brownian motion the Doppler shift occurs or in other words change the wavelength of the incident light. This Change in wavelength related to the size of the particle. Using autocorrelation function of scattered light intensity it is possible to compute the diffusion coefficient and measure sphere size distribution of the particle.
Keywords: Atocorrelation function, Brownian motion, Dynamic Light Scattering (DLS), Diffusion coefficient, Hydrodynamic diameter, PhotoMultiplier Tube (PMT).
