The　microscopic　and　spectroscopic　properties　of　the　metallic　photonic　crystals　(MPCs)　are　controlled　by　adjusting　the　annealing　temperature　after　the　direct　writing　process　using　interference　ablation.　Strong　surface　tension　and　possible　nano-scale　flowability　of　the　molten　gold　nanoparticles　enable　reshaping　and　aspect-ratio　adjustment　of　the　gold　nanostructures　during　the　annealing　processes.　This　consequently　leads　to　the　tuning　of　the　spectroscopic　response　of　localized　surface　plasmon　resonance　by　changing　the　annealing　temperature,　thus　enhancing　the　flexibility　and　extending　the　application　of　the　fabrication　technique　using　interference　ablation.　(C)　2012　Elsevier　B.V.　All　rights　reserved.
