Lanthanide luminescence has many important applications in anion sensing, protein recognition, nanosized phosphorescent devices, optoelectronic devices, immunoassays, etc. Luminescent europium complexes, in particular, act as light conversion molecular devices by absorbing ultraviolet (UV) light and by emitting light in the red visible spectral region. The quantum yield of luminescence is defin...

We report the design and evaluation of pH responsive luminescent europium( iii ) probes that allow conjugation to targeting vectors monitor receptor internalisation in cells.

The 3+ and 2+ oxidation states of europium have drastically different magnetic and spectroscopic properties. Electrochemical measurements are often used to probe EuIII/II oxidation state changes, but a full suite of spectroscopic characterization is necessary to demonstrate conversion between these two oxidation states in solution. Here, we report the facile conversion of an europium(III) tetra...

Z. Naturforsch. 51 b, 806-810 (1996): received November 9, 1995 Europium Intermetallic Compounds, Crystal Structure EuPdSn and EuPtSn were prepared from the elements in tantalum tubes at 1070 K and in­ vestigated by X-ray diffraction on both powder as well as single crystals. They crystallize with the TiNiSi type structure of space group Pnma and with Z = 4 formula units per cell. Both structur...

We describe an immunofluorometric assay for human pancreatic phospholipase A2 based on time-resolved fluorescence. The labeled antibody technique in combination with the time-resolved 1-s fluorometric detection of the europium label, which essentially eliminates all background fluorescence, resulted in a high sensitivity (20 ng/L) and a wide (5000-fold) linear range. Nonspecific binding was min...

A europium-doped MOC shows interesting metal and ligand-centered luminescence response from pH 2 to 11.

We demonstrate that magnetic dipole transitions provide an additional degree of freedom for engineering emission spectra. Without the need for a high-quality optical cavity, we show how a simple gold mirror can strongly tune the emission of trivalent europium. We exploit the differing field symmetries of electric and magnetic dipoles to selectively direct the majority of emission through each o...

the sorption and desorption behaviors of eu(iii) from aqueous solutions with cation exchange resins containing carboxyl groups (d155 resin) were studied in terms of varied eu(iii) concentration, adsorbent dosage, ph, contact time and temperature. batch shaking sorption experiments were carried out to evaluate the performance of d155 resin in the removal of eu(iii) from aqueous solutions. the lo...

Recovery and reuse of materials is important for a circular economy. In recent years the recovery of critical metals from end-of-life products has received increased attention. Various streams, e.g. permanent magnets, nickel metal hydride batteries and fluorescent lamps are considered targets for the recovery of rare earth elements (REEs). The last can be a source of up to six different REEs: e...
