In the minor actinides recovery process from high-level liquid waste, analysis for complex structure in organic solvent has been studied to strip minor actinides from a loaded solvent efficiently. In this study, Eu was used as a simulated material of minor actinides, and organic solvents containing Eu complexes were prepared. The composition of Eu complexes in organic solvents was confirmed by particle induced X-ray emission. In addition, the ion beam induced luminescence was measured, and the basic data for the complex structure were obtained.
