Random silver nanowires embedded in Ni-doped zirconia (Zr0.9Ni0.1Oy) dielectric were prepared by coprecipitation technique. The morphology and structure properties of Ag/Zr0.9Ni0.1Oy (AZNx; where ‘‘x’’ is [Ag]/ [Zr0.9Ni0.1Oy] = x) nanocomposites were studied by X-ray diffraction, scanning electron microscopy, atomic force microscopy, transmission electron microscopy, and X-ray photoelectron spectroscopy techniques. Interesting negative permittivity and permeability behaviors of AZNx are found. The experimental data of the negative permittivity are fitted well by Drude model. These results have important implications for the realization of double-negative properties in AZNx as a promising candidate for the double-negative materials.
