我们利用双光子诱导共沉淀技术来制备金和银纳米结构。金和银纳米颗粒在溶液中以及在薄膜中产生。在这两种情况下，与等离子体共振相关的吸收峰被清楚地观察到，并发现随着颗粒的生长而变化。此外，我们还表明，这种技术也允许制造具有良好质量的2D和3D金属纳米结构。光学应用的潜力进行了讨论，并说明了一些例子。特别是，我们观察到高效率的发光和强大的可调扩散。
We are using the technique of two-photon induced photoprecipitation to fabricate gold and silver nanostructures. Gold and silver nanoparticles are produced in solution as well as in thin films. In both cases an absorption peak associated with the plasmon resonance is clearly observed and is found to vary as particles grow. In addition, we show that this technique also permits the fabrication of 2D and 3D metallic nanostructures with a good quality. The potential for optical applications is discussed and illustrated on some examples. In particular, we observe high efficiency luminescence and strong tunable diffusion.
