Luminescent Terbium/Europium chelates-based Silica Nanoparticles : Stability and Incorporation Efficiency measured by Radioactive Probe

, , , , , ,
We describe an original method based on europium-chelated radioactive measurements to investigate and compare the incorporation (by a reverse microemulsion-mediated sol-gel process without covalent bond) and the stability of two different organolanthanides into silica nanoparticles. [...]
