Abstract

Development and applications of new nanomaterials and nanocomposites that include metal nanoparticles have received much attention in the last years. However, there are relatively few studies concerning basic physical characteristics of the dielectric function at the nanoscale, which is needed for predicting their optical and plasmonic response. The size-dependent complex dielectric function of metal Fe, Pt, Ti, Ta, Al, and V nanoparticles (NPs) is calculated for the first time for an extended wavelength range from UV to FIR, based on experimental bulk complex refractive index measurements in the mentioned range at room temperature. Calculation is based on a “top-down” approach, based on a stepwise modification of the Drude model. Bulk plas...
