在本文中制作了CaAl4O7：Tb3+，Ce3+新荧光材料。烧结温度为1 300 ℃，烧结环境为N2+5%H2还原气。TEM实验结果表明样品的粒度小于1 μm。X-射线和HRTEM实验证实，样品的晶格点阵十分规则，而且没有发现掺杂和助溶剂对基质结构的影响，表现出十分好的材料质量。光学实验观测到对应于Tb3+离子的5D4到7FJ(J＝6，5，4，3)的跃迁发射峰在485，545，590和620 nm。CaAl4O7：Tb3+，Ce3+降低了基质结构的不确定性，同时保持了Tb3+发光中心的特性。

We had made CaAl4O7：Tb3+，Ce3+ samples by sintering the sample at 1 300 ℃ in reduction environment N2+5%H2.Emission lines corresponding to the 3D4 to 7FJ (J＝6,5,4,3) optical transitions of the Tb3+ ions were observed at 485,545,590 and 620 nm respectively.The particle size of the sample was controlled to less that 1 μm.The lattice of the sample was rather regular in atomic scale and showed very good quality.CaAl4O7：Tb3+,Ce3+ materials can reduce structure uncertainty of the host and remain typical optical properties of the Tb3+ emitting center.
