摘要

•Five different Ag@SiO2 nanoparticles were prepared.•Four kinds of europium and terbium complexes were synthesized.•The complexes were found to adsorbed on the surface of Ag@SiO2 nanoparticles.•The luminescence effect of the nanoparticles on different complexes is different.•The different excitation wavelength had a great influence on the luminous intensity.
