A　localized　surface　plasmon　(LSP)　coupling　nanorod　mu　LED　using　graphene　as　a　transparent　conductive　electrode　structure　was　demonstrated.　The　optical　performance　of　the　mu　LED　with　LSP　coupling　is　enhanced　by　about　36%　in　external　quantum　efficiency　and　84%　in　photoluminescence　measurements　as　compared　with　the　LSP-free　sample.　This　LSP　coupling　enhancement　relies　on　the　very　large　sidewall　area　provided　by　the　nanorod　structure　and　the　zero　distance　contact　between　the　nanoparticles　and　nanorods.　This　work　provides　a　broad　prospect　for　the　application　of　LSP　in　the　mu　LED　field.
