Preparation and Characterization of Smcl3(THF)3 and Sm(BH4)3(THF)3 Complexes
The synthesis of SmCl3(THF)3 from SmCl3.6H2O is described. The reaction of SmCl3(THF)3 with NaBH4 in dry THF gave white microcrystalline tris (tetrahydroborato) tris (tetrahydrofuran) samarium (III), Sm(BH4)3(THF)3. The vibrational and magnetic properties of Sm(BH4)3...
متن کاملStable lanthanide luminescence agents highly emissive in aqueous solution: multidentate 2-hydroxyisophthalamide complexes of Sm(3+), Eu(3+), Tb(3+), Dy(3+).
Efficient lanthanide (Ln) luminescent probes require good ligand-to-metal energy transfer and high aqueous stability. A family of ligands based on 2-hydroxyisophthalamide chelating units is reported. These form highly stable, eight-coordinate Ln complexes. Several of these (Ln = Sm, Eu, Tb, Dy) emit in the visible region with good ligand-to-lanthanide energy transfer. The absolute quantum yield...

متن کامل1 Yb 3 + and Yb 3 + - Eu 3 + luminescent properties of the
The luminescence of Yb in the oxyborate Li2Lu5O4(BO3)3 is reported. At low temperature, in addition to the usual ytterbium infrared emission, this phosphor presents an emission in the ultraviolet (λmax= 345 nm) which corresponds to the transition from the charge transfer state (O-Yb) to the 4f levels of Yb. The temperature quenching Tq50% is equal to 120K. The infrared emission studied at room ...
متن کاملLuminescence properties of sol–gel derived spherical SiO2@Gd2(WO4)3:Eu 3+ particles with core–shell structure
Monodisperse, core–shell structured SiO2@Gd2(WO4)3:Eu 3+ particles were prepared by the sol–gel method. The samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy, transmission electron microscopy, photoluminescence (PL) and low-voltage cathodoluminescence (CL). PL and CL study revealed that the core–shell structured SiO2@Gd2(WO4)3:Eu 3+ particles sho...
