【Abstract】

Eu 3+-activated BiOCl layered phosphors induced by doping Zn 2+ were prepared by traditional solid reaction method, and the effects of Zn 2+ ion dopants (0–20 mol%) on the photoluminescence properties were characterized by X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), Fourier transform infrared absorption (FT-IR), excitation and emission spectra, and luminescence decay curve measurement. It is found that increase of concentration of Zn 2+ ion dopants almost has no influence on the structure of BiOCl crystals but decreases the emission intensity of Eu 3+ ion at first and then increases it, accompanying with continually enhancing luminescence lifetime of Eu 3+ ions. The comparative experiments suggest that the results are involved in special layered structure of BiOCl semiconductor. Zn 2+ ions will be incorporated into interlayer space of the BiOCl layered crystals when the concentration of Zn 2+ ions ≤ 10%. Then, Zn 2+ ions tend to incorporate into crystal lattices by substituting Bi 3+ ions. Different doping mechanisms of Zn 2+ may change Eu 3+ lifetime and modify energy transfer efficiency from the host, leading to above emission behavior of Eu 3+ ion dopants. The result is helpful to improve the performance of novel red Eu 3+ doped BiOCl phosphor and to understand the emission property of rare earth ion in layered phosphors.
