Here, different strategies to manipulate light with plasmonic nanoparticles, nanoresonators, as well as large area hybrid nanostructures are addressed and discussed. Changes of the local density of optical states by controlling the spatial and spectral position of the hot spots or the coupling of emission to plasmonic or photonic modes leads to remarkable options for the enhanced light trapping in organic thin films, the spectral and directional modification and enhancement of fluorescence and electroluminescence. Further we present possibilities for tuning the localized surface plasmons resonances of nanoparticles for an optimal spectral overlap with different gain materials.
