- Abstract
- Yttrium(III) and lanthanide(III) vanadates corresponding to the general formula AVO(4) (A = Y, Pr, Sm, Eu, Gd, Dy, Er) were prepared by a nonconventional soft chemistry route in which coordination compounds of the different elements to be incorporated were used as molecular precursors. In this case, EDTA-based yttrium(III), lanthanide(III) and vanadium(V) complexes were synthesised, characterised and used as precursors for the preparation, of zircon-type AVO(4) materials at a moderate temperature of 800 degrees C, as evidenced by XRD and Raman analyses. Solid solutions such as Y1-x-PrxO4 and Y1-x-GdxVO4 were also obtained. Linear correlations between chemical compositions and lattice parameters or Raman shifts were observed. SEM was used to characterise the particle size and morphology. ((D Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008).
