We report a novel and efficient method for the laser direct writing of two-dimensional silver structures. Multiphoton absorption of a small fraction of the output of a Ti:sapphire oscillator is sufficient to photoreduce silver nitrate in a thin film of polyvinylpyrrolidone that has been spin-coated on a substrate. The polymer can then be washed away, leaving a pattern consisting of highly interconnected silver nanoparticles. We report the characterization of the silver patterns using scanning electron and atomic force microscopies, and demonstrate the application of this technique in the creation of diffraction gratings.
我们报道了一种用于激光直接写入二维银结构的新颖且高效的方法。钛宝石振荡器输出的一小部分光的多光子吸收足以在旋涂于基底上的聚乙烯吡咯烷酮薄膜中光还原硝酸银。然后可以将聚合物洗掉，留下由高度互连的银纳米颗粒组成的图案。我们报道了使用扫描电子显微镜和原子力显微镜对银图案的表征，并展示了该技术在制造衍射光栅方面的应用。
