Silver Sodalites: Novel Optically Responsive Nanocomposites
A range of novel silver sodalites has been synthesized. These solid state microstructures are viewed as “packaged” silver salts comprised of nanoassemblies of silver cations tetrahedrally organized with various charge balancing anions. A collection of physicochemical characterization techniques (UV-VIS reflectance/emission/excitation; luminescence lifetimes; FT-Far/Mid-IR; XPS; TGA-MS; 29Si, 27Al, 23Na MAS-NMR; Rietveld XRD profile analysis) have been employed to investigate the structure and properties of the parent silver sodalites, as well as the chemical and physical transformations of the encapsulated silver salts that relate to a number of interesting transducer effects. Intercavity communication between entrapped silver microaggregates and expanded-metal superlattice ideas will be considered briefly. The utilization of the silver sodalites in high resolution imaging/printing and high density write/read/erase data storage applications are also considered.
