摘　　要：采用高温固相法合成了一系列Ce^3+、Tb^3+及Ce^3+/Tb^3+掺杂的Zn3(BO3)(PO4)荧光粉,研究了材料的发光性能。结果显示,在Ce^3+、Tb^3+在Zn3(BO3)(PO4中,分别发射蓝和绿色光,同时,Ce3+的发射光谱和Tb^3+的激发光谱有明显的重叠,通过分析Ce^3+、Tb^3+共掺时,材料的荧光寿命曲线,发现在Zn3(BO3)(PO4:Ce^3+/Tb^3+中,Ce^3+对Tb^3+有明显的能量传递,在实验范围内,能量传递效率可以达到68%。A series of Ce3+,Tb3+ and Ce3+/Tb3+ doped Zn3(BO3)(PO4) phosphors were synthesized by a high temperature solid-state method and the luminescence properties were investigated.The results show that Ce3+ and Tb3+ doped Zn3(BO3)(PO4) phosphors can produce blue and green light,respectively.There is a spectral overlap between the emission spectrum of Zn3(BO3)(PO4):Ce3+ and Zn3(BO3)(PO4):Tb3+,and the synthesized results show that there is an energy transfer from Ce3+ to Tb3+ ions by the decay curves,and the energy transfer efficiency can reach 68% in our experiment.
