Effect of diode-diode interactions on the characteristics of the absorption spectra of granular films and colloidal suspensions of gold and silver nanoparticles

摘要

This paper discusses the possibility of using the concepts of intermolecular-interaction theory and the effective-field-dispersion method to model how resonance and inductive-resonance dipole-dipole interactions affect the frequencies of the plasmon-absorption bands of granular films and colloidal suspensions of gold and silver nanoparticles. It is shown that the results of theoretical calculations carried out in terms of the quasi-static approximation agree well with the available experimental data. (C) 2015 Optical Society of America.
