摘要

通过高温固相法制备了Re_xTb_(2-x)Mo_3O_(12)(Re=Eu,Er; x=1%,3%,5%)材料.研究了不同Eu~(3+)、Er~(3+)掺杂浓度对Tb_2(MoO_4)_3发光性能的影响.X射线衍射结果表明:合成样品为纯相,Eu~(3+)、Er~(3+)的掺杂并不改变Tb_2(MoO_4)_3的晶体结构.激发光谱和发射光谱结果表明:随着Eu~(3+)掺杂浓度的增大,Tb_2(MoO_4)_3发光强度提高;随着Er~(3+)掺杂浓度的增大,样品发光强度先增强后减弱,存在浓度猝灭现象.本研究为开发新型发光材料提供了一定的参考.
        The Re_xTb_(2-x)Mo_3O_(12)(Re = Eu,Er;x=1%,3% and 5%) samples were prepared by high temperature solid state reaction.The influence of different doping concentration of Re(Eu,Er) elements on luminescent properties of the Re_xTb_(2-x)Mo_3O_(12) were investigated.X ray diffraction,excitation spectra and emission spectra experiments were performed.It is found that the luminous intensity of Eu_xTb_(2-x)Mo3_O_(12) is increased with the increase of Eu~(3+) concentration,while the luminous intensity of the Er_xTb_(2-x)Mo_3O_(12) is increased first and then decreased with the increasing Er~(3+) concentration.The doping of Eu~(3+) and Er~(3+) does not change the crystal structure of Tb_2(MoO_4)_3.
