摘要：

Plasmonic activity is reported for a series of Au nanoring antennae with 1-5 splits in their geometry. The rings have a radius of 75 nm and splits of 3-6 nm. By controlling the size of the splits, their location and the radius of the ring structure, we can control the number, intensity and frequency of the plasmonic hotspots.
