Outline of Final Research Achievements

The aim of this project was to develop a new in situ XAFS technique, which enables simultaneous measurement of XRD for the same sample. The prototype in situ XAFS and XRD cell was tested for the measurement of a Tb doped alumina film. The Tb doped alumina film exhibits photo- and electroluminescent properties after calcination treatments. The in situ measurements were conducted to elucidate the mechanism how the active structure was formed and clarify the exact structure of the active site. The experiments were conducted under a flow of inert gas, increasing the temperature from room temperature to 700 degree C. Tb LIII-edge XAFS and XRD of alumina were successfully observed. The results indicated that Tb ions were atomically dispersed in alumina. They were not incorporated in the framework of alumina but were located on the surface of alumina nanoparticles.
