Electroless Deposition of W‐doped Ag Dendrites from HF Solution

Abstract

AbstractA simple method was developed for the preparation of W‐doped Ag dendrites by using electroless deposition from hydrofluoride solution. The samples characterized by XPS, XRD, SEM and TEM techniques, show that the growth of silver is leading and can not be changed essentially by tungstate ions in the Ag‐W binary system. A doping mode of W element was proposed, i.e., the doping of W may occur during silver deposition through chemisorption‐chemical bonding of oxygen atoms of tungstate dimer with silver. Cyclic voltammetry was employed to determine the chemical bonding energy between silver and oxygen.
