A series of complexes the type [Ln(Se2P(phenyl)2)3(CH3CN)x] (x = 1 or 2) have been synthesized and structurally characterized for Ln La–Lu (excluding Pm). The are straightforward to prepare crystallize soluble in solvents typically used nanoparticle synthesis. Solution-phase thermolysis these formed lanthanide diselenide LnSe2–x nanosheets, La–Ho, except Eu, which EuSe. By contrast, smallest lanthanides Er–Lu Ln2Se3 nanomaterials. dichalcogenides rare-earth analogues transition metal exhibit...
Rare-earth manganese pyrochlores (R2Mn2O7) are frustrated magnetic materials, which previously have only been accessed using expensive high-pressure and high-temperature synthesis. In the present work, we demonstrate a convenient synthetic approach to synthesize R2Mn2O7 at ambient pressure. A series of (R = Y, Ho-Lu) were prepared by simple cost-effective molten salt method NaCl KCl as flux. Moreover, phase-selectivity was demonstrated for yttrium oxides (YMnO3 Y2Mn2O7) variation synthesis...
In targeting reduced valent lanthanide chalcogenides, we report the first nanoparticle synthesis of mixed-valent ferromagnets Eu3 S4 and EuSm2 . Using divalent halides with bis(trimethylsilyl)sulfide oleylamine, prepared nanoparticles EuS, , SmS1.9 Sm3 All phases were identified using powder X-ray diffraction, transmission electron microscopy was used to confirm morphology size, magnetic susceptibility measurements for determining ordering temperatures valence. The UV/Vis, Raman...
Neodymium tritelluride is a layered van der Waals material, with correlated electronic properties including high mobility, charge density waves, and antiferromagnetism. We developed solution synthesis method to form free-standing nanosheets of NdTe
We have investigated the mechanism of relaxivity for two magnetic resonance imaging contrast agents that both employ a cluster-nanocarrier design. The first system termed Mn8Fe4-coPS comprises cluster Mn8Fe4O12(L)16(H2O)4 or Mn8Fe4 (1) (L = carboxylate) co-polymerized with polystyrene to form ∼75 nm nanobeads. second Mn3Bpy-PAm used Mn3(O2CCH3)6(Bpy)2 Mn3Bpy (2) where Bpy 2,2'-bipyridine, entrapped in ∼180 polyacrylamide Here, we investigate rate water exchange clusters, and corresponding...
