Hydrothermal synthesis and improved luminescent properties of nanosheet-based rare earth orthoborates lantern-like assemblies

The precursor prepared by co-precipitation method was sintered at various temperatures to synthesize crystalline manganese tungstate (MnWO4). Sintered MnWO4 showed the best crystallinity at a sintering temperature of 800 °C. Rare earth ion (Dysprosium; Dy3+) was added when preparing the precursor to enhance the magnetic and luminescent properties of crystalline MnWO4 based on these sintering temperature conditions. As the amount of rare earth ions was changed, the magnetic and luminescent characteristics were enhanced; however, after 0.1 mol.%, the luminescent characteristics decreased due to the concentration quenching phenomenon. In addition, a composite was prepared by mixing MnWO4 powder, with enhanced magnetism and luminescence properties due to the addition of dysprosium, with epoxy. To one of the two prepared composites a magnetic field was applied to induce alignment of the MnWO4 particles. Aligned particles showed stronger luminescence than the composite sample prepared with unsorted particles. As a result of this, it was suggested that it can be used as phosphor and a photosensitizer by utilizing the magnetic and luminescent properties of the synthesized MnWO4 powder with the addition of rare earth ions.

The Eu

A tripodal ligand, 2-acetylpyridine-tris(2-aminoethyl)amine (L), pyridine-N-oxide and their ternary complexes with rare earth nitrates have been synthesized. These new complexes with the general formula of Ln·L·PyNO·(NO3)3·nH2O (where Ln = La, Nd, Tb, Pr, Eu, n = 1~3 ) were characterized by elemental analysis, IR spectra, thermal analysis and molar conductivity. All the complexes are stable in air. The results show that the lanthanide ions in each complex are coordinated by nitrogen atoms of the ligand, oxygen atoms of PyNO and the nitrates. The fluorescent properties of the Eu(III) and Tb(III) complexes in solid were investigated.
