准渗透纳米结构银薄膜被用作起始形态，通过激光照射同时诱导形状和有序效应的变化。当通过针孔照射时，复杂的指状纳米结构转化为纳米球，纳米球又排列成微圆形图案。这些转变通过透射电子显微镜和原子力显微镜来表征。使用菲涅尔衍射理论解释了观察到的效应。与实验结果吻合良好。这些结果表明，可以通过控制空间参数（例如针孔直径和掩模到样品的距离）来实现精确的图案化工程。
Quasi-percolated nanostructured silver thin films are used as the starting morphology for inducing simultaneously changes in shape and ordering effects by laser irradiation. The complex fingered nanostructures are transformed into nanospheres which in turn are arranged in micro-circular patterns when irradiated through a pinhole. These transformations are characterized by transmission electron microscopy and atomic force microscopy. The observed effects are explained using Fresnel diffraction theory. Good agreement with the experimental results is obtained. These results suggest that precise patterning engineering can be achieved through control of the spatial parameters such as the pinhole diameter and the distance from the mask to the sample.
