Similarly, thermolysis of the rareearthmetal sesquisulfide (γRE 2 S 3), oxysulfide (RE 2 O 2 S) or oxychloride (REOCL) with M 2 S or MCI in an atmosphere of H 2 SN 2 gives MRES 2. The materials were characterised by powder Xray diffraction, scanning electron microscopy (SEM), energy dispersive analysis by Xrays (EDXA), Raman, infrared, magnetic moments and microanalysis.

Rare earth ions are well known luminescent activators in a variety of host lattices and the rareearth activated phosphors have been studied extensively because of their high light output, excellent colour rendering index, energy efficiency and greater radiation stability (Blasse and Grabmeter 1994; Burland et al 1994). Eulytite phosphates have been shown to be better hosts for rare earth ...

Rare earth tuckin complexes have been proposed since the early 1980's. For example, an investigation by Watson regarding the activation of methane and benzene by a methyllutetium complex [(Z5C 5Me 5) 2LuCH 3] n (1, n = 1 or 2) implied the formation of a tuckedin lutetium intermediate (Z5C 5Me 5)Lu{Z 5:Z1C 5Me 4(CH 2)} (2) (Scheme 2). 12 Despite the reactivity and kinetic data ...

The investigation of the rareearth aluminum hydrides during thermolysis shows a decrease of thermal stability with increasing atomic number of the RE element. Rareearth hydrides (REH x) are formed as primary dehydrogenation products; the final products are REaluminum alloys. The calculated decomposition enthalpies of the rareearth aluminum hydrides are at the lower end for reversible ...
