Abstract Surface plasmons can make highly spatial confinement and near-field enhancement at the metal/dielectric interface and decrease optical loss. Here, we introduced detachable aluminum nanoparticles (Al NPs) substrate to enhance CH3NH3PbBr3 perovskite lasing performances, and compared the lasing actions between Al-CH3NH3PbBr3 and prime CH3NH3PbBr3 microcuboid to understand the mechanism. Based on Al surface plasmons coupled excitation in Al-CH3NH3PbBr3 hybrid system, the lasing threshold is dramatically reduced more than 27% and the stimulated emission of CH3NH3PbBr3 improved 10 times.
