Briefly, we experimentally compare the properties of circular nanoapertures milled in gold and aluminium to enhance the fluorescence of dyes diffusing within the nanoapertures. Our main result is that nanoapertures in gold exhibit much higher fluorescence enhancement. We discuss the influence of a noble metal holding plasmonic resonances in the visible range such as gold. Altogether, these results provide crucial knowledge for the design of nanoapertures towards high-efficiency single-molecule analysis.
