Abstract

Role of incident electromagnetic field enhancement and photon density of states with respect to scattering (Raman and Rayleigh processes) and spontaneous emission of photons is discussed. Field enhancement and density of states effects should manifest themselves in the same manner in photoluminescence and scattering processes. Differences in scattering and luminescence enhancement are due to quenching processes which are less pronounced for scattering but crucial for luminescence because of finite internal relaxation processes between excitation and emission events and. We consider recent experimental results on single molecule detection by means of surface enhanced Raman scattering and photoluminescence enhancement of quantum dots and consider possible approaches to engineering of efficient light emitting nanostructures.
