Plasmonic Materials: 3D Aluminum Hybrid Plasmonic Nanostructures with Large Areas of Dense Hot Spots and Long-Term Stability (Adv. Funct. Mater. 10/2017)

A millisecond-laser-direct-writing approach under ambient conditions for designing of a 3D Al hybrid nanostructure supporting dense hot spots with high electric field enhancements over a large area is reported by Jing Yang and co-workers in article number 1605703. The plasmon-enhanced light harvesting ranges from deep UV to the visible, and leads to an averaged SERS performance that is comparable to noble metals.
