Abstract

Existing models for optical properties of metallic particle films differ in their treatment of the mechanisms for particle interaction. For model comparison and improvement we fit the calculated optical spectra to obtained ones experimentally by variation of several structural parameters. The deviation of the model’s structure parameters from those obtained experimentally (by analysis of transmission electron microscope pictures) permits comparison of models. We find that for thermally treated silver island films in the mass thickness range 1–6 nm the particle interaction is described best by a quasi-static dipole–dipole interaction, neglecting retardation effects and mirror dipole effects.
