SPIE Fellow Akhlesh Lakhtakia, editor-in-chief of the Journal of Nanophotonics, recommends "Facile synthesis and patterning of silver nanoparticles for surface plasmon generation," published in the journal in July 2011.
Rapid fabrication of metallic nanoparticles uniformly over large surfaces is very desirable for a host of optical applications such as bio/chemical sensing, SERS, photocatalysis, and solar-energy harvesting. Silver nanoparticles are particularly useful, due to their size-dependent display of localized surface plasmon resonance in the UV/Vis/NIR regimes.
Jayant Kumar of University of Massachusetts Lowell and his coauthors present their facile single-step technique involving the photodecomposition of a photoactive silver nitrite aliphatic amine complex. Decomposition of the silver complex is accomplished using either a UV or Argon ion laser.
The synthesized nanoparticles display absorption peaks that are characteristic of localized surface plasmon resonance. The fabrication technique is industrially scalable.
