Abstract:We investigated several geometric parameters such as the height, width and length, and the contribution of different plasmonic modes on the enhancement factors of aluminum (Al) bowtie nano-antennas (BNAs) on tryptophan’s native fluorescence in the ultraviolet (UV) to visible range. The highest fluorescence enhancement was produced by the tallest BNAs. Analysis revealed that, in tall BNAs illuminated at normal incidence, phase retardation amplified quadrupole resonances which were exploited to obtain high excit… Show more
