Spherical silver (Ag) nanoparticles, triangular Ag nanoprisms, and triangular gold (Au) nanoparticles were separately deposited on the Eu(TTFA)3-doped Su8 films. Compared with the fluorescence of films without nanoparticles, the fluorescence of the doped films was greatly enhanced by the two kinds of the Ag nanoparticles, the enhancement is greater for the spherical Ag nanoparticles than that for the triangular Ag nanoprisms. The fluorescence was quenched for the film with Au nanoparticles. Results show that the nanoparticles can both enhance and quench the fluorescence of the films, which depend mainly on the local surface plasmon resonance (LSPR) of the nanoparticles. When the LSPR of nanoparticles overlaps with the excitation or the emission spectrum of the films, the fluorescence would be enhanced. Otherwise the fluorescence of the films would be quenched.
