通过静电纺丝技术定向排列群体金纳米棒(GNRs),制备了GNRs-纳米纤维复合薄膜。利用偏振依赖的开孔z扫描技术,发现了薄膜的各向异性饱和吸收性质。该定向排列的GNRs-纳米纤维薄膜在光纤激光器领域具有重要的应用前景。
GNRs-nanofiber composite films were prepared by orienting groups of gold nanorods (GNRs) by electrospinning. Using the polarization-dependent aperture z-scan technique, the anisotropic saturated absorption properties of the films were found. The oriented GNRs-nanofibers film has important application prospect in the field of fiber lasers.
