DIMENSIONAL EFFECT IN THE FORMATION OF SECONDARY CHROMOPHORE FLUORESCENCE SPECTRA NEAR THE SURFACE WITH PLASMONIC PROPERТIES
Abstract
The selectivity of plasmonic substrates - plasmonic silver films and plasmonic gold crystals - is developed as selective enhancement of different secondary emission types (Raman or fluorescence) with the use of the same chromophores, excitation conditions, but different sizes of metallic grains at the plasmonic substrate surface. It is conditioned by a different contribution of absorption and scattering cross sections to the extinction cross section for small and large nanoparticles.
