摘要：

Silver　nanoparticles　(Ag　NPs)　thin　film　were　fabricated　by　radio-frequency　(RF)　magnetron　sputtering　on　the　quartz　substrates　in　different　sputtering　time,　then　covered　with　a　layer　of　rubrene　by　means　of　thermal　evaporation.　The　sputtering　time　for　preparation　of　Ag　NPs　could　be　tuned　to　increase　the　spectral　overlap　between　the　emission　spectra　of　rubrene　and　surface　plasmon　resonance　spectra,　so　that　the　surface　plasmon　enhancement　was　improved.　Using　a　Fluorescence　spectrophotometer　(FLS920),　the　photoluminescence　(PL)　intensity　of　the　rubrene/Ag　NPs　thin　film　was　up　to　22　times　higher　than　that　as-deposited　rubrene　thin　film.　It　is　attributed　to　the　energy　transfer　effect　in　the　surface　plasmon　resonance　coupling,　the　surface　plasmons　mediated　emission,　and　light　scattering.　©　(2015)　Trans　Tech　Publications,　Switzerland.
