Abstract
Uniform thin films of gold nanoparticles have been fabricated on gold substrates using a layer‐by‐layer self‐assembly approach (see Figure). The optical properties of these nanoparticle films were characterized using variable‐angle spectroscopic ellipsometry, and the data modeled using a Lorentz oscillator dispersion model. Both the thickness and refractive indices were evaluated simultaneously over a wide wavelength range.
