Rare earth is of great interest because of their unique optical properties, especially the rich luminescent spectra. In this study, we developed a facile one-pot microwave-assisted synthesis of luminescent Eu3+ doped TiO2 nanoparticles and Tb3+ doped ZrO2 nanoparticles. As a result, the emitting centers (Eu3+ and Tb3+) were all well dispersed in the amorphous host oxide materials, leading to high luminescence. The obtained TiO2:Eu3+ and ZrO2:Tb3+ nanoparticles were then encapsulated into PLGA microparticles for bio-applications. These luminescent microparticles were then proven to be highly stable, biocompatible and of low cytotoxicity. We successfully demonstrated the bioimaging of live cells using the red-luminescent TiO2:Eu3+ nanoparticles and green-luminescent ZrO2:Tb3+ nanoparticles embedded PLGA microparticles. The microwave-assisted synthetic methodology can be further developed to be general method to prepare oxide nanoparticles.
