Shape-Controlled Synthesis and Electrical Conductivities of AgPb10SbTe12 Materials

AgPb 10 SbTe 12 crystals with nanocubic and flower-like morphologies have been successfully fabricated by a facile solution route. The sizes and morphologies of AgPb 10 SbTe 12 were examined in relation to reaction temperature, the molar ratio of KOH/Pb(Ac) 2, polyvinyl pyrrolidone (PVP), and solvents. A surface-protected etching growth mechanism has been proposed to elucidate the formation of nanocubes and flower-like crystals. Furthermore, the electrical conductivities of the samples with nanocubic and flower-like shapes were measured to investigate the possible impact of size and morphology on the electrical conductivity.
