摘要

研究了卤代酸锶中镱离子在光学、x射线和同步加速器激发下的发光特性。Sr2(1-x)Yb5O9R的发射光谱由蓝波段和紫外波段组成。前者是由于4f135d在Yb2+离子上产生4f14次跃迁。后者暂定为Yb3+离子的电荷转移发光。讨论了Sr2B5O9R的结构特征和某些制备条件对Yb离子发光行为的影响。

Luminescent properties of ytterbium ions in strontium haloborates

The luminescence e properit4se of ytterbium ions in strongtium haloborates were studied under optical, x-ray and synchrotron excitation. The emission spectra of Sr2(1-x)Yb5O9R consists of a blue and a UV band. The former is due to 4f135d yields 4f14 transtions on the Yb2+ ions. The latter is tentatively assigned to charge transfer luminescence of Yb3+ ions. The influence of the structural features of Sr2B5O9R and some preparative conditions on the luminescent behavior of Yb ions is discussed.
