Assembling a semiconductor quantum supralattice one atom at a time: Nonstoichiometric silver, sodium bromosodalites
- Univ. of Toronto, Ontario (Canada)

The synthetic details and structural, vibrational, and optical properties of a series of novel silver, sodium bromohydrosodalites of the type (8 {minus} p {minus} 2n)Na,2nAg, (2 {minus} p)Br-SOD, where p = 0-2, 2n = 0-8 are reported. These sodalites form a solid solution of empty {beta}-cages interdispersed with Na{sub 4{minus}n}Ag{sub n}Br clusters. Variations in p alter the mean distance between the clusters while changes in n shift the constituents of the clusters from those of an insulator to a semiconductor type. Far-infrared, {sup 23}Na MAS-NMR, optical spectroscopy, and Rietveld refinement of high-resolution powder XRD data show that these materials offer the opportunity to manipulate the extent of collective electronic and vibrational interactions between monodispersed clusters in a perfectly crystalline host.
