| Popis: | The optical properties of small silver particles evaporated onto silica and glass substrates have been studied in the UV and visible spectra as functions of the particle size, shape and filling factor. Absorption spectra are interpreted using an extended Maxwell-Garnett theory, and reflection spectra are interpreted using the Fresnel formula with effective dielectric permittivities. Optical absorption and reflection maxima are caused by collective surface plasma oscillations, and these maxima shift towards longer wavelengths with increasing filling factor. |
