A gel is formed when a mixture of methyl methacrylate(MMA) and styrene(St) is added to tri-isopropoxyl-rare earth(Eu(OPrⁱ)₃, Tb(OPrⁱ)₃ or their mixture), and the rare earth-doped copolymers P(MMA-co-St) are obtained by in-situ polymerization. The copolymers were characterized by dynamic mechanical thermal analysis(DMTA), fluorescence spectro-photometry(FS) and environmental scanning electron microscopy(ESEM). The effects of co-doping of the mixture Eu(OPrⁱ)₃/Tb(OPrⁱ)₃ on the properties of the copolymers were studied with emphasis on their fluorescence property. The results show that, the storage moduli of the copolymers co-doped with the mixture Eu(OPrⁱ)₃/Tb(OPrⁱ)₃ are higher than that of the corresponding P(MMA-co-St), and the characteristic fluorescence strength of Eu³⁺ ions increases by about 100 times due to the energy transfer between Tb³⁺ as a donor and Eu³⁺ as an acceptor.
