Quenching of IR luminescence of erbium, neodymium, and ytterbium beta-diketonate complexes by ligand C-H and C-D bonds

Article Abstract:

A detailed study of the role of CH and CD quenching on the luminescence of [Er.sup.3+], [Nd.sup3+] and [Yb.sup.3+] ions in the Cs[Ln[(HFA).sub.4]] system is presented. The results show that for [Er.sup.3+] ions the rapid luminescence quenching is strongly dependent on the immediate local environment with only a second effect due to more distant CH bonds.

Energetics and thermodynamic stability of the mixed valence ytterbium germanides

Article Abstract:

The thermodynamic stability of the Yb germanides, described as intermediate valence compounds, is analyzed. The high-temperature decomposition reaction of YbGe intermediate phases is studied by Knudsen effusion mass (KEMS) and Knudsen effusion weight loss (KEWL) techniques.
