•Silver nanosphere with good homogeneity and dispersity was synthetized.•The enhancement ratio was relative to the thickness of dye-doped silica layer.•The strongest fluorescence signal obtained as dye-SiO2 layer tuned to 10 nm.•An 11-fold enhancement was realized, compared with the sample without silver core.
Enhancement of the light emission of dye molecules (Ru(bpy)32+) was studied by coating dye-doped SiO2 layer on Ag core. The enhancement ratio was found to be relative to the thickness of dye-doped silica layer. The core–shell Ag@dye-SiO2 nanocomposites have the strongest fluorescence intensities when the thickness of dye-SiO2 layer was tuned to 10 nm. It was found that an 11-fold enhancement of fluorescence signal was realized with Ag@dye-SiO2 nanoparticles, compared to the sample without silver core.
