Claims19
A method of making an article having plasmonic nanoparticles, the method comprising:
- depositing a polyelectrolyte layer on a substrate;
- depositing a first plasmonic nanoparticle layer on said polyelectrolyte layer, said first plasmonic nanoparticle layer having first plasmonic nanoparticles oriented parallel to said polyelectrolyte layer;
- and
- depositing a second plasmonic nanoparticle layer on said polyelectrolyte layer, said second plasmonic nanoparticle layer having second plasmonic nanoparticles randomly oriented in multiple directions to said polyelectrolyte layer.
