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.
