Abstract

Formation of particle aggregates of arbitrary size and shape by lumping of small particles yields extinction and scattering of light that differ from those of isolated particles.

The aggregation process can be followed from extinction and angle-resolved light scattering measurements. Introducing new parameters in angular light scattering, systems containing only isolated clusters were efficiently distinguished from cluster-aggregate systems. This was achieved by evaluation of the measured data in forward and backward scattering direction and at a scattering angle of 90°, resulting in a distinct separation of isolated-cluster systems and cluster-aggregate systems. For measuring the angle-resolved light scattering by noble metal colloidal particle systems, a common photogoniometer setup had to be modified. Changes in scattering and extinction data were qualitatively described by a model that takes into account electromagnetic coupling among clusters in the aggregate.
