（Y，Zn，Sr）_3（P，VO_4）_2：Eu^（3＋），Bi^（3＋）发光性

Studies on Luminescent Properties of (Y, Zn, Sr)_3(P, VO_4)_2: Eu￣(3+), Bi￣(3+)

合成了组成为（Ｙ，Ｚｎ，Ｓｒ）３（Ｐ，ＶＯ４）２：Ｅｕ３＋，Ｂｉ３＋的荧光材料，经射线结构分析确定为Ｚｎ３（ＰＯ４）２结构，属于单斜晶系，空间群为Ｐ２１／ｎ讨论了基质组成对Ｅｕ３＋离子发光性质的影响，用Ｙ３＋取代了一部分Ｚｎ２＋，用ＶＯ取代了一部分ＰＯ．由于基质的４３６ｎｍ发射与Ｅｕ３＋的激发态能级的能量重叠，Ｅｕ３＋产生较强的５９８ｎｍ和６１８ｎｍ发射．另外，掺入少量Ｂｉ３＋能增强Ｅｕ３＋发射．

The phosphors of (Y, Zn, Sr)3(P, VO4)2:Eu3+, Bi3+ were synthesized by solid state reaction. Their crystal structures determined by X-ray powder diffraction belong to the monoclinic system space group P21/n The influence of components on the emission of Eu3+ ions was discussed. A part of Zn2+ was replaced by Y3+ and a part of PO by VO in Zn3(PO4)2. Because of the energy overlap of 436nm emission and Eu3+ excitation state energy of the host, Eu3+ produces more strong 598 and 618nm emis emissions. Adding small amount of Bi3+ can enhance Eu3+ emission.
