Abstract

Color-tunable phosphors Sr0.94MoO4:xEu3+,(0.06 − x)Tb3+ were synthesized rapidly by microwave radiation method with active carbon particle as microwave absorbent. The synthesized phosphors were investigated by X-ray powder diffraction (XRD) and fluorescence spectrophotometer. The effects of the ratio of Eu3+ and Tb3+ on the phase structure and luminescent properties of the phosphors were discussed. The results show that Eu3+,Tb3+-doped samples can be well indexed to the pure tetragonal scheelite-type SrMoO4, indicating that Eu3+ and Tb3+ are effectively doped into the SrMoO4 host lattices. The as-synthesized Sr0.94MoO4:xEu3+,(0.06 − x)Tb3+ phosphors have two luminescent centers (Eu3+ and Tb3+), which can show red and green emissions under ultraviolet light excitation, respectively. Doping concentration of Eu3+ and Tb3+ has great effect on the intensity of emission peaks and the chromaticity of the samples, and the full color between green and red light can be achieved by adjusting the relative concentration of Eu3+ and Tb3+.
