Outline of Final Research Achievements |
In the present study, site selective XAFS measurement method using X-ray excited optical luminescence has been developed and applied to measure XAFS spectra of defect and/or emission site structures in solid materials. In addition, a sophisticated combination of XAFS and EELS, particularly introducing modern mathematical treatments to the EELS and EFTEM spectrum imaging (EFTEM-SI) allowed us quantitative analysis and visualization of the different chemical states in a solid catalyst. We applied this method to the study on the generation mechanism of the visible light response in nitrogen doped TiO2 catalysts.
