Outline of Final Research Achievements

In this study, we have explored layered mixed-anion compounds as new kinds of natural superlattice. The specific structure of layered mixed anion compounds must leads to development of new structure for quantum effects, because there are large difference of ionic radii, of anions in each layer. We have found several strategy to develop new layered mixed anion compounds, and found more than 100 compounds. We have investigated their functionality especially superconductivity and optical properties. Several compounds show excitonic luminescence due to their layered structure. We have also developed new iron-based compounds with new type block layers, and they show better superconducting properties than other iron-based compounds.
