Figure 6From: Profile Prediction and Fabrication of Wet-Etched Gold Nanostructures for Localized Surface Plasmon ResonanceThe gold nanostructures a before, b during, and c and d after being etched in a 1:10 diluted potassium iodide gold etchant. Prior to etching, 50 nm of gold was evaporated onto 500 nm diameter silica nanospheres at 70°.Scale bars in SEM pictures are 1 μm. Inserts are simulated side views of the gold nanostructuresBack to article page
