Abstract

Mechanisms and experimental performance of photoluminescence and Raman scattering enhancement are considered in the context of their application in novel luminophores and high sensitive spectral analysis. So-called “hot spots” are treated as local areas in plasmonic nanostructures where high Q-factors develop both for incident light frequency and for emitted or scattered light frequency. Feasibility of 10- to 102 -fold enhancement is highlighted for luminescence. Rationale is provided for 1014 enhancement factor for Raman scattering which has been claimed based on experimental observation but to date has never been reported in the theory..
