Site preference for luminescent activator ions in doped fluoroperovskite RbZnF3

With the dual objective of investigating the site preferences of larger sized activator ions and to append luminescence property to the perovskite structured RbZnF3, doping of manganese(II), cerium(III), europium(III) and terbium(III) ions (5 mol%) was carried out. Although cubic symmetry of RbZnF3 was preserved for all the doped samples, site preference of rare-earth ions for the A-site Rb+ leading to an inverse perovskite arrangement has been noticed from careful analysis of lattice parameters from refinement of powder X-ray diffraction data. Undoped RbZnF3 exhibited rod-like morphology in the transmission electron microscopic image. In addition to an intense band around 230 nm assignable to the charge transfer from ZnF3 ? to Rb+, typical transitions of respective dopant ions were observed in their UV–visible spectra. The doped samples showed luminescence in blue, green and red regions and time decay experiments suggested uniform dispersion of them without any clustering effect. The lower phonon energy of RbZnF3 matrix by virtue of the presence of heavier rubidium at the A-site together with its doping with rare-earth ions resulting in an inverse perovskite like arrangement could favour their utility in various practical applications.

Investigation of the Rb-W-O system in connexion with the superconducting properties of the hexagonal tungsten bronzes

The previous studies of the superconducting properties of the hexagonal tungsten bronzes have repeatedly come up against the lack of reproducibility of the data and, at the first place, of the data relating to the stability of superconducting state. We revisited this problem and identified the main causes of these contradictory data in RbxWO3, among which the major one is the ordering of the alkali atoms. Our study has emerged onto a determination of the x dependence of the order-disorder transition, of the lattice parameters and of the superconducting transition temperature Tc. We have also clarified the crystal structure and examined the mechanisms involved in the oxidation and reduction of this compound. Finally, we have assembled our data to draw a plausible Rb-W-O phase diagram.

A New Route to Alkali Metal Aluminum Hydrides MAlH4 with M = Na, K, Rb, Cs and Structural Features for The Whole Family with M = Li to Cs.

MAlH4 with M = Na, K, Rb and Cs were prepared in toluene or hexane from an exchange reaction between LiAlH4 and an halide of the corresponding metal dissolved in the medium as Ziegler-type complex with triethylaluminum. The best process involves the equimolar complexes MF-AlEt3 with fluorides. The four MAlH4 were quantitatively obtained with a purity > 99% (wt). RbAlH4 and CsAlH4 have the same barite-type structure as KAlH4 (orthorhombic, Z = 4), with parameters (?, .+-..002) a:b:c : 9.253:5.950:7.599; 9.981:6.075:7.953, respectively.
