Theoretical Calculation of the Optical Absorption of Fractal Colloidal Aggregates Using a Multiple Scattering Formalism
The optical response of fractal aggregated gold colloids is described considering the interaction between particles due to two separated contributions resulting from short and long range effects. The systems will be studied in an effective medium formalism, where the scattering units are clusters of two spheres. The short range interaction will be taken into account via cluster effects, while the long range interaction will be taken into account by considering a multiple scattering effective medium analysis.
