A novel method for fabrication of 2D and 3D metal nanoparticle structures and arrays is proposed. This technique is based on laser-induced transfer of molten metal nanodroplets from thin metal films. Metal nanoparticles are produced by solidification of these nanodroplets. The size of the transferred nanoparticles can be controllably changed in the range from 180 nm to 1500 nm. Several examples of complex 2D and 3D microstructures generated form gold nanoparticles are demonstrated.
提出了一种制备二维和三维金属纳米颗粒结构及阵列的新方法。该技术基于激光诱导从薄金属膜转移熔融金属纳米液滴。这些纳米液滴凝固后形成金属纳米颗粒。转移的纳米颗粒尺寸可在180纳米至1500纳米范围内可控地变化。展示了由金纳米颗粒生成的几个复杂二维和三维微结构的实例。
