| Abstract: | In this study, Zn_4B_6O_(13), Eu-and Tb-doped Zn_4B_6O_(13) 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 Zn_4B_6O_(13), but obviously affected the morphology of Zn_4B_6O_(13) 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 Zn_4B_6O_(13), Zn_4B_6O_(13):Eu and Zn_4B_6O_(13):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. |
