Octylamine‐coated silver nanoparticles with an average size of 10 nm were synthesized and added to the AZO powder as fillers to increase the density of the sintered target. The resulting A g– AZO nanocomposite powder was formed into compacts by a uniaxial pressing process. It was found that the addition of octylamine‐ coated silver nanoparticles can increase the density of AZO powder compacts by ~ 4% after sintering. The optimum content of silver addition is about 0.13 wt%. It is suggested that the melted silver fills the void space between agglomerate pores and enhances the interconnection between nanocrystalline AZO powders. The films deposited using the here‐synthesized A g– AZO target showed lower resistivity and high carrier concentration compared with the one using AZO target.
