Electron localization phenomena in complex carbides of rare earth and transition metals

Electron-phonon coupling in the rare-earth metals.

Molecules containing rare-earth atoms solely bonded by transition metals.

Although metal-metal bonding is important in the chemistry of both solid-state intermetallic compounds and molecular species, the study of this bonding is limited by the compounds available and it is rarely possible to identify connections between these two areas. In this study, molecular intermetalloids [Ln(ReCp(2))(3)] (Ln = Sm, Lu and La) have been synthesized that contain lanthanoid metals ...

Preparation of rare earth metals

The production of over 400 grams of pure gadolinium metal by reduction of the anhydrous chloride by calcium in tantalum vessels is described; yields were over 97%. The use of the same techniques in an attempt to prepare yttrium metal were partially successful.

The RARe eARTh MeTAlS And TheiR CoMpoundS Thermal Analysis of Rare earth nitrate Mixtures

26 Einstein J. Biol. Med. (2008) 24:26-31. A method of analysis is proposed which utilizes the characteristic melting points of the hydrated salts and the liquidus curves of the binary salt mixtures for the estimation of the composition of rare earth mixtures. Several binary salt systems were investigated, employing very pure simple and double rare earth nitrates to provide basic information co...

Cathodoluminescence from Amorphous and Nanocrystalline Nitride Thin Films Doped with Rare Earth and Transition Metals

Rare earth (RE) ion luminescence has long been used in laser and optical fiber communications technology. Bulk RE doped oxides were widely used in color phosphors for Cathode Ray Tubes. The wide band gap (WBG) semiconductors and insulators have been used for visible emission at 300 K from RE ions since the reports first by Zanata (Zanatta and Nunes 1998) for Er in silicon nitride (photoluminesc...
