Figure 3From: Au nanostructure arrays for plasmonic applications: annealed island films versus nanoimprint lithography Measured extinction spectra of random NSA samples produced via thermal annealing of gold island films. Normal incidence unpolarized light extinction spectra for samples R1 to R9 with different initial gold island film thickness exhibit peaks located in the wavelength range from 576 to 809 nm. Inset: the table with respective NSA geometrical parameters.Back to article page
