提出了一种快速制备大尺寸周期性纳米颗粒阵列（直径40-200 nm）的新方法。这种方法是基于纳米球光刻和激光诱导转移的组合。制造的球形纳米颗粒部分嵌入聚合物基底中。它们排列成六边形阵列，可用于传感应用。在可见光谱范围内，灵敏度为365 nm/RIU，品质因数为21.5的光学传感器被证明。
A novel method for high-speed fabrication of large scale periodic arrays of nanoparticles (diameters 40-200 nm) is developed. This method is based on a combination of nanosphere lithography and laser-induced transfer. Fabricated spherical nanoparticles are partially embedded into a polymer substrate. They are arranged into a hexagonal array and can be used for sensing applications. An optical sensor with the sensitivity of 365 nm/RIU and the figure of merit of 21.5 in the visible spectral range is demonstrated.
