History Of

The luminescence of trivalent lanthanide ions has found applications in lighting, lasers, optical telecommunications, medical diagnostics, and various other fields. This introductory review presents the basics of organic and inorganic luminescent materials containing lanthanide ions, their applications, and some recent developments. After a brief history of the discovery, purification and early spectroscopic studies of the lanthanides, the radiative and nonradiative transitions of the 4f electrons in lanthanide ions are discussed. Lanthanide-doped phosphors, glasses and crystals as well as luminescent lanthanide complexes with organic ligands receive attention with respect to their preparation and their applications. Finally, two recent developments in the field of luminescent materials are addressed: near-infrared luminescent lanthanide complexes and lanthanide-doped nanoparticles.

General Method

A general method for the determination of the conformations of molecules in solution which uses paramagnetic lanthanide ions as perturbing probes of nuclear magnetic resonance spectra is described in outline. Several examples of conformational studies on the lanthanide complexes of amino acids and peptides are given. It is clear that there are two very different groups of lanthanide complexes characterized by those of Pr in and Tm Ill. The conformations of the Tm III complexes are used to initiate an examination of peptide chain folding and to re-examine the nature of hydrophobic interactions.
