Abstract:
A low-coherence fiber optic dynamic light scattering technique is used to measure the particle size distributions of colloidal suspensions with different volume fractions. We detect electric field autocorrelation function of the singly backscattered light from a sample and use the CONTIN algorithm to obtain the particle size distributions. As a result, in the range of volume fractions from 0.01 to 0.10 of monodispersive colloidal suspensions, the mean particle size with the deviation within 4% and the polydispersity approximate 5% can be determined for particles of different radii. The results demonstrate that the low-coherence fiber optic dynamic light scattering technique is effective in measuring particle size of colloidal suspensions.
