• The enhancement of surface plasmon-coupled emission (SPCE) by the synergistic effect of silver nanocubes (AgNCs) and graphene oxide (GO) on gold film has been observed with the enhancement factor over 30. The enhancement mechanisms were investigated through simulating the electromagnetic (EM) field patterns of near field and testing different concentration of AgNCs and thickness of dye layer. The enhancement was mainly triggered by the high electromagnetic field of AgNCs, the interaction between localized surface plasmons (LSP) and propagating surface plasmons (PSP) and the assistance of GO. This synergistic enhancement strategy provides a simple way to increase SPCE signal and enable develop a new fluorescence-based detection system. [Display omitted] •The introduction of AgNC and GO could enhance SPCE signal synergistically.•The enhancement factor was over 30.•Concentration of AgNC and thickness of dye layer could affect the enhancement result.•This enhancement is due to high EM field of NC, interaction between LSP and PSP, and the assistance of GO.•This strategy provides a way to improve sensitivity for fluorescence-based platform.
