Abstract

We present that an intensity distribution of optical near field induced around photo-irradiated polystyrene spherical nanoparticles was transcribed on a film of azo-containing urethane-urea copolymer. The transcription was attained by a topographical change of the polymer surface, and the change was observed using an atomic force microscope. We have observed distinguishable dent surface structure using particles 28 nm in diameter.
