Self-assembled glassy plasmonic nanostructures: fabrication and properties
In my talk I will refer to a recently developed technique of silver nanoparticles’ growth on the glass surface and in its subsurface. The technique is based on self-organization and makes it possible to arrange silver nanoparticles in a prescribed manner on the glass surface. Optical properties of these nanostructures are governed by the surface plasmon resonance effect and can be tuned by the nanoparticles’ reshaping or by changing the dielectric environment. The latter can be done through the deposition of highly-refractive dielectric and allows strong enhancement of second optical harmonic generation even at nonresonant wavelength. In addition to these effects, the applicability of fabricated silver nanoisland films in surface-enhanced Raman spectroscopy will be discussed.
