Au-nano-particles production by pico-second ultra-violet laser deposition in Au-ion doped PMMA film

Abstract

We have demonstrated a novel technique for Au-nano-particle production in a polymer thin film based on the pico-second ultra-violet laser deposition. The Au-nano-particles produced by this technique were finely controlled without aggregation and the average size was ∼20 nm. We also investigated holographic grating formation in the polymer film by pico-second ultra-violet laser deposition technique.
