Transmission electron microscopy study of Ni-rich, Ag-Ni nanowires

By Chandan Srivastava and Rajesh Kumar Rai


Present work provides an electrodeposition based methodology for synthesizing Ni-rich, Ag-Ni nanowires using an alumina template. Ag-Ni system shows negligible solid solubility in the bulk. Detailed structural and compositional characterization of as-synthesized nanowires using transmission electron microscopy technique revealed a two phase microstructure. Regions along and near the nanowire axis contained crystalline Ag-Ni solid solution phase with Ag-rich composition. Whereas, regions away from the axis and near the nanowire boundary predominantly contained nanocrystalline Ni-rich, Ni-Ag solid solution phase. (C) 2013 Elsevier B. V. All rights reserved
