Scattering efficiency of clusters composed by aggregated spheres

摘要: We present a detailed study of the variation average scattering cross section various aggregates titanium dioxide crystallites as function their sizes and shapes. To perform analysis, we use recursive T-matrix algorithm that developed. show how aggregation phenomenon can tremendously decrease local properties white paint film consequently affects its hiding power. also compare results with equivalent spherical volume approximation which is used in particle size analysis using static or dynamic light-scattering methods. those methods should be handled care.
