The local structure around the dopant atom in Nd(8 mol%):LaF3 single‐crystal scintillator is analyzed by X‐ray fluorescence holography experiments in combination with a sparse modeling algorithm. The average local environment of Nd is reconstructed up to large distances of about 12 Å and confirms a substitution of La atoms with Nd with only small crystal lattice distortions. The experimental findings are substantiated by comparison with reference data from La holograms and with computationally generated holograms based on a model structure of the dopant site.

X射线荧光全息术在Nd：LaF3中杂质位点的局部结构
通过X射线荧光全息术结合稀疏建模算法，分析了Nd（8 mol％）：LaF 3单晶闪烁体中掺杂原子周围的局部结构。Nd的平均局部环境可重构到大约12Å的较大距离，并确认La原子被Nd取代，而晶格畸变很小。通过与La全息图的参考数据进行比较，并与基于掺杂位点模型结构的计算得出的全息图进行比较，从而证实了实验结果。
