The first complex picosecond filament, namely a filament of terbium(III) p-hydroxybenzoate, is observed. The filament is the only example of Ln(III) ion two-photon absorption in a complex. A transparent, colorless and mechanically robust thin film, as well as a supramolecular gel, of this complex are prepared in a facile manner and exhibit strong luminescence. The thin film is characterized in ...

Sexithiophenes 1a and 1b, in which a 4-(dimethylamino)phenyl unit is incorporated as an end-capping group, were synthesised and characterised by cyclic voltammetry, absorption spectroscopy and UV-vis spectroelectrochemistry. Additionally, their ability to function as effective luminescence quenchers for quantum dot emission was studied by photoluminescence spectroscopy and compared with the per...

-The adsorption of Sn(IV)TPyP (mesotetrapyridylporphyrin) in sodium hectorite was studied using ultraviolet-visible and luminescence spectroscopy. The adsorbed complex was found to demetallate forming the TPyP dication as the clay is dehydrated. This process was found to be reversible indicating that the Sn 4+ ion remains in the vicinity of the porphyrin upon demetallation. The luminescence spe...

The luminescence and scintillation properties of ZnO single crystals were studied by photoluminescence and X-ray-induced luminescence (XRIL) techniques. XRIL allowed a direct comparison to be made between the near-band emission (NBE) and trap emissions providing insight into the carrier recombination efficiency in the ZnO crystals. It also provided bulk luminescence measurements that were not a...

In connection with the chemical modification of protein, the photooxidation of histidine (His), tryptophan (Trp) and carnosine by singlet oxygen O2) is investigated by a Eu3+ luminescence probe ATTA-Eu3+ and UV Raman spectroscopy under physiological conditions (pH 7.5). The solutions ontaining both the luminescence probe ATTA-Eu3+(1× 10−5 M) and the different concentration of the biological tar...

A heterometallic lanthanide complex has been prepared by sequential deprotection and complexation of an orthogonally protected ligand: luminescence and NMR spectroscopy have been used to probe the integrity of the complex.

A determination of the excited-state zero-phonon line (ZPL) energies in 3 d -configuration ion is possible from a set Racah ( B and C ) crystal-field splitting parameters Dq ), vice versa. Therefore, conjunction with Sugano−Tanabe energy-level diagram are used as means describing effects electron−electron repulsion within metal complexes coordination chemistry. The purpose this article to obtai...
