研究了Ｅｕ~（２＋）、Ｍｎ~（２＋）共激活的ＳｒＭｇＰ_２Ｏ_７的发光性质、浓度与荧光性质的关系。Ｅｕ~（２＋）和Ｍｎ~（２＋）的发射光谱分别在４００ｎｍ及６７０ｎｍ附近，它们是Ｅｕ~（２＋）的５ｄ－４ｆ跃迁和Ｍｎ~（２＋）的~４Ｔ_１（~４Ｇ）－~６Ａ_（１ｇ）（~６Ｓ）跃迁发射，实验结果表明：Ｅｕ~（２＋）对Ｍｎ~（２＋）的荧光发射有较强的敏化作用，Ｍｎ~（２＋）对Ｅｕ~（２＋）的荧光寿命和强度也有显著影响．
The luminescent properties, concentration and fluorescence properties of SrMgP 2 O 7 co-activated by Eu ~ (2 +) and Mn ~ (2+) were studied. The emission spectra of Eu 2+ and Mn 2+ are near 400 nm and 670 nm, respectively. They are the 5d-4f transitions of Eu 2+ and the ~ 4T_1 (~ 4G) - ~ 6A_ 1g) ~ (6S) transition emission. The experimental results show that Eu 2+ has a strong sensitizing effect on the fluorescence emission of Mn 2+, Strength also has a significant effect.
