Fabrication　of　bimetallic　networks　consisting　of　periodically　arranged　gold　nanoparticles　(AuNPs)　embedded　with　a　grid　of　silver　nanowires,　where　solution-processing　materials　or　techniques　are　involved　in　all　of　the　fabrication　procedures,　is　reported.　Annealing　of　the　colloidal　gold　nanoparticles　and　the　photoreduction　of　the　silver　ions　in　the　mixture　solution　of　AgNO3　and　polyvinyl　pyrrolidone　in　water　are　the　main　processes.　The　key　to　this　fabrication　is　that　the　AuNP　array　is　used　as　the　mask　for　the　photoreduction　of　silver　ions　into　nanowires,　where　the　silver　nanowires　are　thus　located　between　the　AuNPs.　Two　sets　of　dipolar　and　quadrupolar　plasmons,　as　well　as　their　respectively　coupled　resonance　modes,　are　observed　in　the　measurements　and　specified　using　theoretical　analysis.　Thus,　the　bimetallic　photonic　structures　not　only　show　enhanced　and　extended　resonance　spectrum　due　to　the　overlap　of　multiple　localized　surface　plasmons　but　also　induce　plasmonic　hetero-interfacial　interaction　between　the　closely　adjacent　AuNPs　and　silver　nanowires.
