In this paper,St(o)ber silica particles were decorated with polyethyleneimine and silver nanoparticles and Eu-polyoxometalates were grafted on the surface of polyethyleneimine/silica spheres.The hybrid SiO2/Eu-polyoxometalates/Ag particles were characterized by IR,UV-vis,luminescent spectra,scanning electron microscopy,transmission electron microscope,and cyclic voltammetry (CV),respectively.The hybrid particles show the bright red emission under UV light which can be observed by naked eyes.
