Dark-Field Scattering and Local SERS Mapping from Plasmonic Aluminum Bowtie Antenna Array

On the search for the practical plasmonic materials beyond noble metals, aluminum has been emerging as a favorable candidate as it is abundant and offers the possibility of tailoring the plasmonic resonance spanning from ultra-violet to the infrared range. In this letter, in combination with the num...
