Abstract
We present here an original process combining top-down and bottom-up approaches by annealing a thin
gold film evaporated onto a hole template made by etching a PS-PMMA copolymer film. Such process allows a
better control of the gold nanoparticle size distribution which provides a sharper localized surface plasmon
resonance. This makes such route appealing for sensing applications since the figure of merit of the Au
nanoparticles obtained after thermal evaporation is more than doubled. Such process could besides allow to tune
the localized surface plasmon resonance by using copolymer with various molecular weight and thus be
attractive for surface enhanced raman spectroscopy.
