在本研究中,利用低于烧蚀阈值的arf准分子激光(193 nm)照射,在钠-石灰-硅酸盐玻璃中产生了等离子体Au和Au/Ag纳米结构。为此,在纯的和银/钠离子交换的浮法玻璃上涂上一层金,然后用激光照射。利用光谱学测量得到的420 ~ 620 nm之间的表面等离子体共振可以验证Au和Au/Ag纳米颗粒的形成。通过小角度x射线散射实验,可以观察到纯Au和Ag粒子以及双金属Au/Ag纳米粒子。这些结果表明,在准分子激光照射下,这种方法可以在玻璃表面产生空间选择的等离子体纳米结构。
In this study, plasmonic Au and Au/Ag nanostructures in soda-lime-silicate glasses have been generated by means of ArF-excimer laser irradiation (193 nm) below the ablation threshold of the glass. For this purpose pure and silver/sodium ion-exchanged float glasses have been coated by gold and then irradiated by the laser. The formation of Au and Au/Ag nanoparticles could be verified by the surface plasmon resonances between 420 and 620 nm, which were obtained by optical spectroscopy. Both, pure Au and Ag particles as well as bimetallic Au/Ag nanoparticles, could be observed by means of small angle X-ray scattering experiments. These results demonstrate that such procedures enable the spaceselected generation of plasmonic nanostructures in glass surfaces by excimer laser irradiation.
