Sm@C(2v)(3)-C(80) has been separated from the carbon soot produced by electrical arc vaporization of graphite rods doped with Sm(2)O(3) and purified. Its structure has been determined by single crystal X-ray diffraction using cocrystals obtained from either Ni(II)(octaethylporphyrin) (Ni(II)(OEP)) to form

The Eu(2+) → Tb(3+) → Sm(3+) energy transfer scheme has been proposed to realize the sensitization of Sm(3+) ion emission by Eu(2+) ions. Following this energy transfer model, near-UV convertible Sm(3+)-activated orange phosphors have been obtained in Sr3Y(PO4)3:Eu(2+), Tb(3+), Sm(3+)
