| Outline of Final Research Achievements |
In this work, we succeeded to establish operando soft X-ray absorption and emission spectroscopic (SXAS and SXES) techniques, which enable us to simultaneously evaluate electronic structures in occupied and unoccupied orbitals of functionalized oxides while controlling temperature, atmosphere, and polarization. The developed techniques were applied to investigate the electronic structures of complex oxides containing 3d transition metals for the solid oxide fuel cell cathodes under their operating conditions. The developed operando SXAS and SXES techniques are expected as a powerful tool for the deep understandings of materials' functions and their natures by clarifying the electronic structures under their usage environments.
