The effects of the local dielectric environment on the surface-plasmon resonances of annealed gold-island films are studied experimentally and modeled theoretically. Gold- island films were annealed at 600 degree(s)C to produce spheroidal shape particles which exhibit well-resolved resonances in polarized, angle-resolved, absorption spectra. These resonances are shifted in different amounts by the depolarization effect of the surrounding medium (liquids with various refraction indices). Cross-section calculations based upon non-retarded, single-particle, dielectric interaction for these various configurations are presented and found to be in good agreement with the experimental observations.
