Nanoscale spatial analysis of Cs-containing clay minerals by means of synchrotron radiation photoemission electron microscopy

Yoshigoe, Akitaka

In this symposium, the results of nanoscale spatial analysis of clay minerals artificially containing Cs using synchrotron radiation photoemission electron microscopy are talked as an invited tutorial. Despite of its insulating properties, precise analysis of distribution maps of the constituent elements and chemical states of both Cs and Fe atoms were succeeded due to the proper sample treatments. The model of Cs adsorption into clay minerals is discussed based on the data of pinpoint X-ray absorption spectra for Cs and Fe core-levels. Future perspective of the application of synchrotron radiation photoemission electron microscopy are also talked.
