Synthesis and spectroscopic studies of Zn4B6O13 and Eu/Tb single-doped Zn4B6O13 phosphors

In this study, Zn4B6O13, Eu-and Tb-doped Zn4B6O13 phosphors were prepared by conventional solid state reaction method and the samples were characterized by X-ray diffraction（XRD）, scanning electron microscopy（SEM） and photoluminescence spectroscopy（PL）. The doped rare-earth ions had little influence...

Summary:In this study, Zn4B6O13, Eu-and Tb-doped Zn4B6O13 phosphors were prepared by conventional solid state reaction method and the samples were characterized by X-ray diffraction（XRD）, scanning electron microscopy（SEM） and photoluminescence spectroscopy（PL）. The doped rare-earth ions had little influence on the crystal structure of Zn4B6O13, but obviously affected the morphology of Zn4B6O13 particles. The PL results indicated that the 5% Eu-doped sample and 1% Tb-doped sample had the highest intensity in their respective different concentrations doped samples. The CIE chromaticity coordinates indicated that Zn4B6O13, Zn4B6O13：Eu and Zn4B6O13：Tb showed the three basic colors of blue, red and green, respectively. Evidently, the white light could appear only at appropriate intensity of blue, red and green components.
