Novel elastic scattering model for the understanding of the Anomalous transmittance for Au nanoparticle layer.
The optical transmission spectra of several samples of gold nanoparticle layers were examined using a modified Drude model proposed with a novel elastic scattering parameter, gamma'. Although the measured transmission spectra deviated from the simple calculation from Mie scattering, it was explained well by the modified model assuming elastic and inelastic scattering in the form of the collision frequency of free electrons within a metal particle due to the particle boundary. The particle-size and inter-particle-distance dependences of gamma' were extracted within the framework of the proposed model from the curve of best fit of the transmittance spectra.
