The modelling of fractal clusters growth and calculation of their optical spectra
I. Bolesta, R. Hrytskiv, I. Kolych
The relationship between the structure of fractal clusters and their optical spectra has been established. 2D simulation of the cluster growth has been performed within the framework of particle-cluster and cluster-cluster models. The calculation of fractal cluster spectra has been carried out by means of discrete dipole approximation method. It was demonstrated, that considering the interaction between fractal cluster elements allows to observe long-wavelength bands of the surface plasmonic resonance. The peaks positions of these bands are red shifted with respect to the resonant peaks of the non-interacting particles. Essential results of the present research are in good agreement with the experimental optical studies of nanodisperse systems
