Abstract

Abstract : 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.
