Abstract：

We　present　an　all-metal　metamaterials　for　high-performance　refraction　index　sensor,　consisting　of　an　array　of　all-metal　nano-mushrooms　with　three-dimensional　nanocavities.　The　nanocavities　could　greatly　increase　near-field　optical　field　and　therefore　light　can　be　extremely　confined　into　the　nanocavity,　leading　to　a　prominent　enhancement　of　near　fields.　As　a　result,　the　sensor　shows　significant　color　varying　with　small　refraction　index　changes　and　the　sensitivity　is　453.71nm/RIU.　The　demonstrated　all-metal　metamaterial　offers　great　potential　for　microscale　imaging　and　high-performance　optical　sensing.　Copyright　©　(2018)　by　Chemical　and　Biological　Microsystems　Society.　All　rights　reserved.
