Co-precipitation synthesis and characterization of Bi3+, Eu3+ co-doped nanocrystal Gd2WO6 phosphors.
Eu3+ single-doped and Bi3+/Eu3+ co-doped nanocrystal Gd2WO6 phosphors were successfully synthesized via a co-precipitation reaction. The structure and morphology of the phosphors were characterized by using X-ray powder diffraction (XRD) and field emission scanning electron microscopy (FE-SEM). The influence of Bi(3+)-doping concentration on the excitation and emission spectra was studied. It was found that the introduction of Bi3+ can greatly affect the charge transfer band and the luminescence intensity of Eu3+ but does not cause a change in the profile of emission spectra of Eu3+.
