In this Letter we discuss the plasmonic scattering and fluorescence enhancement properties of silver triangular nanoprisms synthesized by a chemical reduction method. Plasmonic platforms (PPs) were made by air-dried self-assembly of the silver triangular nanoprisms onto a gold mirror. Fluorescence enhancement was investigated using methyl-azadioxatriangulenium chloride (Me-ADOTA-Cl) dye in PVA deposited on PPs. Confocal microscopy results showed a 15-fold enhancement of the dye overall, with over 50-fold enhancements on 'hot spot' regions. The presence of silver nanoprisms significantly reduced the lifetime of the fluorophore. The preparation of silver triangular nanoprisms and observed emission data are highly reproducible.
