Abstract

Tb(Asprin)3,Phen/SiO2, nanospheres were synthesized by a microemulsion method. They have a uniform diameter of ∼ 40 nm, and show the characteristic fluorescence of Tb3+ ions. TEM imaging indicated that the hybrid nanospheres are core/shell structure with fine spherical surfaces and Tb (Asprin)3 Phen has been successfully enveloped in the SiO2 spheres as chromophores cores. IR absorption spectra and photoluminescence spectra propose that the hybrid nanoparticles are promising materials for biological application.
