Abstract
Ytterbium 2,6-naphthalenedicarboxylate (Yb2(nda)3·4H2O) and ytterbium 9-anthracenecarboxylate (Yb(ant)3) were obtained for the first time, and it was shown that both of them exhibit ligand sensibilized ytterbium luminescence. Anions antâ and nda2â were tested for the nanoparticle surface modification of YbF3 and model EuF3. The surface modification of the size uniform toroid-like EuF3 nanoparticles with K2(nda) and octahedron-like YbF3 nanoparticles with K(ant) results in the significant luminescence enhancement due to lanthanide carboxylate formation on the particle surface. Such a surface modification leads to the particle size decrease, while their shape remains the same.
