Chemical co-precipitation synthesis of luminescent BixY1−xVO4: RE (RE = Eu3+, Dy3+, Er3+) phosphors from hybrid precursors

Abstract

Using novel synthesis technology, novel luminescent materials of BizY0.95−xEu0.05VO4, BixY0.97−zDy0.03VO4 and BixY0.98−xEr0.02VO4 were prepared. An in situ co-precipitation technology was used to assemble the hybrid precursors. Rare earth coordination polymers with aromatic carboxylic acids were used as the precursors of rare earth oxide components, and polyethylene glycol (PEG) and ammonium vanadate (NH4VO3) were composed to assemble inorganic/organic hybrid polymeric dispersing media. Their microstructure and micromorphology have been analyzed by X-ray powder diffraction (XRD) and scanning electronic microscope (SEM). All the emission spectra showed the characteristic absorption of Eu3+, Dy3+ and Er3+, respectively, in the host of YVO4–BiVO4.
