The effect of the plasmonic enhancement of dye fluorescence in poly(vinyl butyral) films containing Ag/SiO2 core-shell nanoparticles has been thoroughly studied. It has been shown that the magnitude of this effect can be quite large (up to 5 times) even for a dye having a very high quantum yield (coumarin 7). Therewith, it substantially depends on the size and concentration of Ag/SiO2 particles and the quantum yield of a dye. The results obtained are discussed with involvement of mechanisms reported in the literature for plasmonic enhancement of fluorescence of dyes characterized by high and low quantum yields.

This shell thickness makes it possible to exclude the quenching of dye fluorescence almost completely.
For convenience, we use this term for plasmonic NPs as well, although the term “extinction spectra” would be more adequate in this case, because such structures can both absorb and scatter incident radiation.
It should be emphasized that no marked change is observed in the molar extinction coefficient of the dye under our experimental conditions.
