For the first time, ternary CuAgSe dendrites on a Ag foil substrate have been synthesized at room temperature by inheriting the dendritic structures of Ag 2 Se nanocrystals, and Cu nanoparticles and Se powders were used to feed the growth in aqueous ammonia solution. The new nano approach for the fabrication of CuAgSe dendrites can be regarded as a successful chemical alternative to the recently developed technique for electrochemical atomic layer epitaxy deposition for chalcogenides. The transformation process and mechanism from the binary Ag 2 Se phase to the ternary CuAgSe phase are discussed along with analysis their of thermodynamic, kinetic, and crystallographic properties.
