An electrochemical method is developed to quantitatively modify and spectroscopically monitor the size and shape of Ag nanotriangles fabricated by nanosphere lithography (NSL) on an indium tin oxide (ITO) electrode surface. AFM and SEM results demonstrate that the preferential order of electrochemical oxidation for a nanotriangle is, surprisingly, bottom edges first, then triangular tips, then out-of-plane height.
开发了一种电化学方法，用于在氧化铟锡（ITO）电极表面对通过纳米球光刻（NSL）制备的银纳米三角形的尺寸和形状进行定量修饰和光谱监测。原子力显微镜（AFM）和扫描电子显微镜（SEM）结果表明，纳米三角形电化学氧化的优先顺序令人惊讶地是底边先于顶角，然后是面外高度。
