摘要
本文是对无机光谱烧孔的典型材料ＢａＦＣｌ（０．５）Ｂｒ（０．５）：Ｓｍ（２＋）的发光动力学过程进行的探索．通过实验得到了５Ｄ２、５Ｄ１、５Ｄ０→７Ｆ０的荧光强度、荧光衰减曲线随温度的变化关系，对５Ｄ２→４ｆ５ｄ带的热激活、５ＤＪ间的无辐射弛豫，５ＤＪ→７Ｆ０的辐射跃迁等过程进行了分析．
his paper reports studies on luminescent processes of BaFCl0.5Br0.5: Sm2+, which is a typical inorganic material of hole-burning. By measuring the dependence of fluorescent intensities and the decay of 5D2,5D1,5D0→7F0 transition, a mode has been proposed to discribe the process of thermal activation of 5D2→ 4f5d, nonradiative transition between 5DJ and radiative transition of 5DJ→7F0.
