A　red-green-blue　plasmonic　random　laser　is　achieved　in　a　multilayer　structure,　which　is　fabricated　by　spin-coating　three　polymer　solutions　successively　on　a　silica　substrate.　Under　optical　pumping,　strong　amplification　of　the　polymer　radiation　can　be　observed　due　to　the　localized　surface　plasmon　resonance　of　silver　nanoparticles　embedded　in　the　multilayer　structure.　Red-green-blue　random　lasing　is　simultaneously　obtained　from　the　sample　based　on　the　enhanced　scattering　strength　of　silver　nanoparticles.　These　results　are　useful　for　designing　compact　integrated　random　laser　sources.　(C)　2017　Optical　Society　of　America
