| Outline of Final Research Achievements |
We have attempted to create innovative functions unique to mixed anion compounds, targeting applications in photocatalysts and photoelectrodes, secondary battery components, phosphors, and electronic materials. In the study of energy-conversion-type photocatalysts, we found that anion-doped titanium dioxide, layered oxynitrides, and oxyfluorides, which had not been candidates for investigation due to technical issues and preconceptions, could be new visible light responsive photocatalysts. Some of the anion-doped oxides were also shown to be effective as secondary battery materials. For phosphor materials, we have established a guideline for controlling excitation and emission wavelengths that is not limited to material systems through band control by anion coexistence. In the study of electronic materials, unique electronic properties associated with complex anionization were observed in many systems.
