采用固相反应法制备了Ba3Bi(PO4)3：Sm3+荧光粉。用X射线衍射仪对荧光粉的晶体结构进行了表征。研究了Ba3Bi(PO4)3：Sm3+的发光性质。优化的Ba3Bi(PO4)3：0.06Sm3+组成的荧光粉在300-500 nm范围内有多个激发带，表现出很好的发光性能。在紫外光373、401和蓝光467 nm的激发下，荧光粉在563、599、646和709 nm处呈现红色发光，分别对应于4G5/2→6HJ(J=5/2、7/2、9/2和11/9)跃迁。计算出的临界距离为21.0？用Van Uitert模型确定了Sm3+离子间的能量传递类型为d-d相互作用。典型样品Ba3Bi(PO4)3：0.06Sm~(3+)在401 nm激发下的色度坐标为(0.59，0.38)。
Ba3Bi(PO4)3:Sm3+phosphors were prepared via solid state reaction process. The crystal structure of the phosphor was characterized by XRD. The PL properties of Ba3Bi(PO4)3:Sm3+were investigated. The optimized phosphor with the composition of Ba3Bi(PO4)3:0.06Sm3+presents the several excitation bands from 300 to 500nm, and exhibits very good luminescence properties. Under the excitation of ultraviolet 373, 401 and blue 467nm, the phosphor presented red luminescence with dominating emissions at 563, 599, 646 and 709nm, corresponding to4G5/2→6HJ(J=5/2, 7/2, 9/2 and 11/9) transitions, respectively. The critical distance was calculated to be 21.0Å. The energy transfer type between Sm3+ions was confirmed as the d–d interaction by using the Van Uitert model. The chromatic properties of the typical sample Ba3Bi(PO4)3:0.06Sm3+phosphor have been found to have chromaticity coordinates of (0.59, 0.38), under the excitation of 401nm.
