This　research　explores　the　interaction　between　silver　films　and　dispersed　silver　nanowires　(Ag　NWs)　in　the　context　of　generating　random　laser　emission.　To　achieve　random　lasing,　we　use　a　mixture　of　Rhoda　mine　B　(RhB)　dye　and　a　polyvinyl　alcohol　(PVA)　matrix　as　the　gain　medium.　The　combination　of　silver　components　plays　a　crucial　role　in　trapping　and　controlling　light.　The　surface　characteristics　of　the　film,　including　its　roughness　and　the　interplay　between　localized　and　extended　surface　plasmons　significantly　affect　the　performance　of　the　random　laser　(RL).　The　laser＇s　threshold　is　closely　linked　to　the　thickness　of　the　film,　which　is　influenced　by　its　surface　roughness.　Additionally,　variations　in　film　thickness　lead　to　wavelength　modulation,　ranging　from　597　nm　to　606　nm,　primarily　due　to　the　reabsorption　of　RhB.　Moreover,　this　research　demonstrates　the　intriguing　capability　to　tune　emission　wavelengths　in　response　to　temperature　changes,　promising　precise　wavelength　control　for　plasmonic　devices　and　potential　applications.　©　2024　Institute　of　Physics　Publishing.　All　rights　reserved.
