It is the first time to synthesize the hybrid Ag 2S–Ag 3SBr superionic conductor nanoparticles with faceted-spherical and polyhedral morphologies, as well as their large-scale ordered arrays. [Display omitted] ► Synthesis of hybrid superionic–superionic conductor nanocomposites. ► Mixed ionic conductive properties. ► Fabrication of high-quality hybrid Ag 2S–Ag 3SBr superionic–superionic conductor nanoparticles. ► Ionic conductivity, tunable ionic conductive properties, nanoscale integrated circuits. We report a simple aqueous-solution route to synthesize hybrid Ag 2S–Ag 3SBr superionic conductor nanoparticles with faceted-spherical and polyhedral morphologies at low temperature. The morphological control was achieved by adjusting the H + concentration in the presence of cetyltrimethylammonium bromide, which was used as both a Br − source and a capping reagent. The hybrid nanoparticles could self-organize into large-scale ordered arrays, and have potential applications in fabricating photonic crystals, mixed superionic conductors, high energy density batteries and near-infrared photoluminescent devices.
