説明

In this study, we prepared two types of europium (Eu)-doped nanoparticle, yttoria and titania and investigated their photophysical properties and biocompatibilities. These particles do not inhibit cell culture, even at higher concentrations. The obtained nanoparticles had a strong and narrow red photo-luminescent peak. The narrow emission was observed even when the particles were uniformly doped into a polymer film. These results suggest that they can be used for applications not only in optoelectronic devices but also in biomedical devices for bioimaging and luminescent biomedical materials.
