Matrix-induced synthesis and photoluminescence of M3Ln(VO4)3:RE (M = Ca, Sr, Ba; Ln = Y, Gd; RE = Eu3+, Dy3+, Er3+) phosphors by hybrid precursors

Using rare earth coordination polymers with salicylic acid as precursors, composing with the polyethylene glycol (PEG) as dispersing media, the phosphor particles of M3Ln(VO4)3:RE (M = Ca, Sr, Ba; Ln = Y, Gd; RE = Eu3+, Dy3+, Er3+) were firstly synthesized via a novel modified in situ chemical co-precipitation technology. Their micromorphology and particles have been analyzed by X-ray powder diffraction (XRD) and scanning electronic microscope (SEM), which indicate that these materials have the micrometer size. And all the characteristic transitions of the doped rare earth ions can be detected in all the host lattices.
