A　wedge-shaped　random　laser　consisting　of　disordered　silver　nanowires　embedded　in　a　dye-doped　polymer　film　was　fabricated　by　using　a　press-coating　method.　The　optical　feedback　was　supported　by　the　scattering　effect　and　the　localized　plasmonic　enhancement　of　silver　nanowires　in　the　wedge-shaped　resonator,　facilitating　a　coherent　random　lasing　action.　The　lasing　wavelength　can　be　tuned　continuously　from　561　nm　to　578　nm　by　simply　changing　the　excitation　position　along　the　thickness　gradient　of　the　wedge　shaped　resonator,　which　was　attributed　to　the　reabsorption　of　R6G.　Besides,　as　the　thickness　increased,　more　lasing　modes　were　observed.　These　properties　can　be　used　in　wavelength　tuning　and　mode　selecting.　The　design　of　wedge　shaped　resonator　provides　simple　approach　of　a　mull-wavelength　random　lasing　emission,　promoting　the　improvement　of　lighting　source.
