Luminescent polymer nanoballs were synthesized by self-organization process via two steps. First, a solution of a mixture of Eu(III) complex and polymer dissolved in THF solvent was gradually diluted with water and then the volatile THF solvent was gradually evaporated from the mixture. The polymers used in this work were poly(methylmethacrylate) (PMMA). The size of Eu(III)-encapsulated polymer nanoball was controllable by adjusting the concentration of the complex and the volume ratio of water to THF. The morphology of the fabricated polymer nanoball was confirmed by FE-SEM. The photophysical properties of polymer nanoballs were investigated by excitation and luminescence spectra. Also we observed cation can give rise to emission quenching. The cation quencher used in this work were Cu2+,Cd2+and Cr3+.The emission quenching of Eu-(III)-encapsulated polymer nanoball were investigated by UV, luminescence spectra.
