| 摘 要： | 我们合成了六种Eu2+激活的碱土金属氟卤化物MFX:Eu2+(M=Ca、Sr或Ba;X=Cl、Br或I)。研究了它们的荧光发射光谱和激发光谱,讨论了Eu2+离子的跃迁发射随基质晶体组成和结构变化的规律。根据晶体场理论,按照C4v点对称性,计算得到在MFCl:Eu2+(M=Ca、Sr或Ba)晶体中Eu2+离子的4?65d1激发态能级分裂的数值。

| Abstract: | Six Eu2+-doped alkaline earth fluoride halides MFX (M = Ca, Sr or Ba; X = Cl, Br or I ) were synthesized by solid slate reactions. The composition and structure-dependence of the radiative transitions of Eu2+ in those hosts have been discussed according to their fluorescence emission and excitation spectra. The splitting energy levels of 4?65d excited state of Eu2+ in the crystal field of MFXmatrices (M = Ca, Sr or Ba) have been calculated. |
