Lithium intercalation into double rare earth chromates
(Elsevier B.V., 1994-07-01)
Lithium intercalation into double rare earth chromates was carried out. It was found that the compounds NaxLi1-xLa(CrO4)2 belong to the NaLa(CrO4)2 structural type and may be recommended as fast ionic conductors. At small ...
Advances in rare earth spectroscopy and applications
(American Scientific Publishers - ASPValencia, 2014-02)
Rare earth (RE) elements are prime constituents in a large amount of innovative materials and several technological advances would not be possible without their contribution. In this review, recent progress in the field ...
Ligand-rare-earth ion energy transfer in coordination compounds. A theoretical approach
(Elsevier B.V., 1997-04-01)
A theoretical approach to the energy transfer process that occurs between a ligand and a rare-earth ion in luminescent complexes is presented. A discussion on the energy transfer mechanisms involved and on the associated ...
Precipitation of rare earth phosphates from H3PO4 solutions
(Gordon Breach Sci Publ Ltd, 1996-01-01)
A study of several factors has been carried out in order to determine their influence on rare earth phosphates precipitation from H3PO4 solutions obtained after the treatment of the Kola phosphate rock.
Optical emission and electron capture of rare-earth trivalent ions located at distinct sites in SnO(2) thin films
(Elsevier B.V., 2009-01-01)
We present photoluminescence and decay of photo excited conductivity data for sol-gel SnO(2) thin films doped with rare earth ions Eu(3+) and Er(3+), a material with nanoscopic crystallites. Photoluminescence spectra are ...
Exponential depletion of neutral dangling bonds density (D-0) by rare-earth doping in amorphous Si films
(ELSEVIER SCIENCE BVAMSTERDAM, 2013-08-02)
In this work we study the effect reduction in the density of dangling bond species D-0 states in rare-earth (RE) doped a-Si films as a function concentration for different RE-specimens. The films a-Si-1_(x) REx, RE=Y3+, ...
Influence of rare earth doping on the structural and catalytic properties of nanostructured tin oxide
(Springer, 2008-05-01)
Nanoparticles of tin oxide, doped with Ce and Y, were prepared using the polymeric precursor method. The structural variations of the tin oxide nanoparticles were characterized by means of nitrogen physisorption, carbon ...
Thermal and structural analysis of germanate glass and thin films co-doped with silver nanoparticles and rare earth ions with insights from visible and Raman spectroscopy
(2016-11-01)
This paper reports on the thermal and optical properties of germanate glasses GeO2–PbO co-doped with silver nanoparticles and rare earth ions (Tm3+, Er3+ and Yb3+) with a focus on the thermal diffusivity (D). The presence ...
Exponential depletion of neutral dangling bonds density (D-0) by rare-earth doping in amorphous Si films
