Surface　enhanced　spectroscopy　such　as　surface　enhanced　Raman　spectrum　(SERS)　and　surface　enhanced　fluorescence　have　been　investigated　extensively　in　the　past　two　decades.　Herein,　we　present　experimental　evidence　to　demonstrate　the　existence　of　a　new　surface　enhanced　spectroscopy,　namely,　surface　enhanced　electrochemiluminescence　(SEECL).　Our　investigation　indicates　that　the　electrochemiluminescence　(ECL)　response　of　the　Ru(bpy)32+-tri-n-propylamine　(TPrA)　system　could　be　significantly　enhanced　when　the　working　electrode　is　modified　with　gold　nanoparticle-SiO2　core-shell　nanocomposites　(AuNP@SiO2).　It　is　worth　noting　that　comparing　with　a　working　electrode　modified　with　pure　SiO2　nanoparticles,　the　electrochemical　responses　of　the　two　electrodes　were　quite　similar,　but　the　ECL　signal　of　the　AuNP@SiO　2　modified　electrode　was　∼5　times　higher　than　that　of　the　SiO2　nanoparticles　modified　electrode.　Thus　we　infer　that　the　localized　surface　plasmon　resonance　(LSPR)　of　the　AuNPs　could　be　a　major　contribution　to　the　ECL　enhancement.　Our　investigations　also　demonstrate　that　the　ECL　enhancement　is　closely　related　to　the　thickness　of　the　SiO2　layer.　As　much　as　10　times　ECL　enhancement　(comparing　with　the　ECL　intensity　of　bare　electrode)　is　observed　under　the　optimal　conditions.　The　possible　mechanism　of　the　SEECL　phenomenon　is　also　discussed.
