IAP-Seminar: "Nano optics of lithographically fabricated metal particles", 5.5.

29 Apr 2009 by Main.RupertHampl in Studium

Metal nano-particles sustain so-called localized surface plasmon (LSP) modes, which are coherent electronic excitations coupled to light in the visible to near infrared spectral range. If excited resonantly, LSP modes lead to optical near field enhancement in a sub-wavelength spatial domain around the metal nano-particle, and related to this are surface enhanced effects, like surface enhanced Raman scattering or -fluorescence.
Regular arrays of quasi-identical, lithographically fabricated metal nano-particles are a flexible platform for systematic research on surface enhanced effects. I will present some recent results, which demonstrate the validity of the electromagnetic SERS model beyond the |E|^4 approximation and show, how in turn surface enhanced effects can be utilized to map the optical near field of the metal nano-particles.
