A　dual-color　plasmonic　random　laser　under　single-excitation　is　achieved　in　an　ultrathin　membrane　doped　with　binary　quantum　dots　and　gold　nanorods.　The　gold　nanorods　tune　the　luminescence　lifetime　and　emission　efficiency　of　quantum　dots.　Under　single　excitation,　low-threshold　random　lasing　is　observed.　Green　random　lasing　at　547　nm　is　＇turned　on＇　and　red　random　lasing　at　630　nm　is　greatly　enhanced　by　the　transversal　and　longitudinal　surface　plasmon　resonance　of　the　gold　nanorods,　respectively.　Speckle-free　color　imaging　is　achieved　by　using　the　proposed　dual-color　random　laser　source.　These　properties　would　facilitate　the　development　of　random　lasers　in　fields　of　illumination　and　imaging.
