Site-selective time-resolved spectroscopy of Eu3+ in KPb2Cl5 has been investigated by using fluorescence line narrowing technique. A crystal field analysis and simulation of the experimental results has been performed in order to parametrize the crystal field at the Eu3+ sites. Three symmetry independent crystal field sites for the rare-earth ion in this crystal were found. A plausible argument about the crystallographic nature of these sites is given.
利用荧光谱线窄化技术研究了K Pb₂Cl₅中Eu³⁺的位点选择性时间分辨光谱。为了确定Eu³⁺位点处的晶体场参数,对实验结果进行了晶体场分析和模拟。发现该晶体中稀土离子有三个对称独立的晶体场位点。给出了关于这些位点晶体学性质的合理推断。
