Abstract Scope |
Heterolayered anion-mixed (HAM) structures consist of two or more alternating sheets, usually built from different anions, e.g., combinations of halide-oxide, chalcogenide-oxide, halide-chalcogenide slabs, and etc. The functional anion separation present in HAM materials can be boosted even further if the HAM structure contains both a covalent and an ionic building block, i.e., a salt inclusion, then it becomes heterolayered anion-mixed salt-inclusion (HAMSI) material. A new family of HAMSI [Na2Cl]GaQ2 (Q = S and Se) containing [Na2Cl]+ salt-inclusion layers alternating with [GaQ2]– sheets obtained through flux crystal growth will be discussed. Novel functionality of heterolayered materials, i. e., radioactive species sorption, will be uncovered as well as we will demonstrate how to use anion-mixed composition advantage to tune the photoluminescence profile of Mn-dopped [Na2Cl]GaS2 single crystals. |
