Figure 4From: Effects of silver impurity on the structural, electrical, and optical properties of ZnO nanowires XPS results of SZO NW. The origin of the chemical bonding and content of Ag element are measured by XPS measurement for the (a) 1SZO, (b) 3SZO, and (c) 5SZO NWs. The insets show that the shape strong peaks originated from the Ag chemical bounding peak (Ag 3d5/2) of the SZO NWs are observed at 369.7 and 369.3 for 3SZO and 5SZO NWs, respectively.Back to article page
