摘要

利用同步辐射光源(德国HASYLAB实验室的SUPERLUMI实验站)和真空紫外激光(157.6nm)对新型蓝光发射长余辉材料Sr

MgSi

:Eu

(0.2%)

(8%)进行了光谱研究。在170nm同步辐射光源激发下

观察到对应Eu

:5d-4f跃迁的477nm发射带和对应Dy

:4f-4f跃迁的两组线谱发射

其中只有来自Eu

的5d-4f发射对长余辉光谱有贡献。在157.6nm激光激发下

除了上述发射外

还明显观察到对应Eu

的红色线谱(590

614

626nm)。结合这些光谱特性

对Sr

MgSi

:Eu

中稀土离子的发光特性以及长余辉发光机理进行了讨论

并提出了Eu

充当空穴陷阱的可能性。
