Abstract

Ag ₂S nanocrystals (NCs) are embedded into a GeS ₂ matrix while controlling the size, shape, and interparticle spacing of the Ag ₂S NCs. We demonstrate that the ionic and electronic properties of these inorganic nanocomposites can be systematically controlled by varying the diameter of the Ag ₂S NCs. We also observe an ionic conductivity enhancement relative to pure Ag ₂S and (GeS ₂) _0.5(Ag ₂S) _0.5 glass.
