SEM images of AgNPs multilayer films of the substrates: (a) Ag/GL-1/0.5-25, (b) Ag/GL-5/2.5-18, and (c) Ag/GL-10/5-6. The top panels present the low magnification (large area) images, and the bottom panels are high magnification (high resolution) images indicating the nanostructures of Ag double-layer films. The insets in (b) and (c) show the high-resolution images of the corresponding Ag dendrites.
