Au, Ag, and Cu nanostructures (NSs) in ionic liquid (IL) media constitute a rich and diverse set of functional materials, with applications ranging from catalysis to sensor fabrication. Owing to the low to negligible volatility of some ILs, it is possible to use novel synthesis methods such ...
暗场光学图像显示,具有4和2 μm线宽的图案化3D Au-2D Ag和3D Au-3D Ag二聚体阵列都呈现出明显的图案颜色,与Au NSs阵列的橙色形成高对比度(图4g-h和16j-k)。值得注意的是,当字母的线宽降低至400 nm时,图案化3D Au-2D Ag和...
Bimetallic Au/Ag hollow nanostar (HNS) nanoparticles with different morphologies were prepared in this work. These nanoplatforms were obtained by changing the experimental conditions (concentration of silver and chemical reductors, hydroxylamine and citrate) and by using Ag nanostars as template nanoparticl...
