Abstract

image

Plasmonic nanostructures are generated by substrate heating. A polymer substrate decorated with clusters of gold particles is shrinking uniformly upon heating. The separation distance between individual nanoparticles is thereby reduced at the same time. The process is visible by a color change of the gold nanoparticle clusters due to plasmonic coupling.
