| 摘 要： | 本文在室温下研究了BaMgF4氟化物中Gd3+和Tb3+离子的荧光光谱以及它们之间的能量传递。在BaMgF4中Gd3+可以直接将激发能传递给Tb3+离子:在Tb3+(4f75d)-Gd3+(4f)-Tb3+(4f8)能量输运过程中,Gd3+离子可起中间体作用。

| Abstract: | Trivalent gadolinium is an important activator and sensitizer.In the present paper, the investigation at room temperature on spectra of Gd3+ ion and energy transfer between Gd3+ and Tb3+ in the systems of BaMgF4:Gd3+ and BaMgF4:Gd3+ Tb3+ are reported. Samples studied were prepared by a solid-state at high temperature from BaF2,MgF2,GdF3 and TbF3 under a flow of hydrogen-nitrogen mixture. |
