We report a surface-plasmon-enhanced random laser emission from highly disordered ZnO nanowires with the assistance of Pt nanoparticles. The underlying mechanism of the enhanced lasing efficiency can be attributed to the energy transfer from Pt nanoparticles to ZnO nanowires due to the strong local field induced by the surface plasmon resonance of Pt nanoparticles. Furthermore, the Pt nanoparticles can serve as an excellent scattering medium, which enormously increases the multiple scattering probability experienced by the random cavity modes. Our strategy provided here is very useful for creating highly efficient optoelectronic devices.
