We report the synthesis and luminescence properties as well as band structure of a series of layered mixed-anion compounds, including a new layered mixed anion compound, Sr3Sc2Ag2Se2O5. The crystal structure, band structure, and optical properties of this new compound and of related compounds Sr3Sc2Cu2Ch2O5 (Ch:chalcogen = S, Se) are presented. The compounds have a common perovskite-like layer of (Sr3Sc2O5)2+ and different semiconductor layers of (Cu2S2)2−, (Cu2Se2)2− or (Ag2Se2)2−. Similar band structures are found for the valence band maximum (VBM), while the structure of the conduction band minimum (CBM) is different depending on the chalcogen species, resulting in the different band gap energies of the compounds. The band gap energies are estimated to be 3.3, 2.9, and 2.4 eV for Sr3Sc2Cu2S2O5, Sr3Sc2Cu2Se2O5, and Sr3Sc2Ag2Se2O5, respectively. Excitonic luminescence is observed near the band edge for all three compounds, with different wavelengths according to their band gap. These optical observations are consistent with the DFT calculations. The luminescence properties of the system can be controlled by changing the composition of the semiconductor-layers, thereby offering large flexibility in material design advantageous for various applications.
