中文摘要:

在这份报纸,我们经由胶体的平版印刷术为金 nanoring 数组的制造报导新策略并且帮助聚合物金 nanoparticles (Au NP ) 自己组装。首先,多分割的聚合物 nanorod 数组经由胶体的平版印刷术被制作。他们然后为 Au NP 吸附被用作模板,它导致了 nanoparticles 在上(4 乙烯基 pyridine )(P4VP ) poly 分割。连续金 nanorings 在黄金的无电的免职以后被形成。金 nanorings 的直径,数量,和间距能被调节。有改变直径的三维的同轴的金 nanorings 能被修改 etch 参数在聚合物 nanorod 上制作。nanorings 在理论上预言的波长展出了光 plasmonic 回声。另外,帮助聚合物的金 nanorings 被免除底层产生自立的 nanorings 的高收益。这个简单、万用的方法也被用来从象钯那样的另外的金属准备 nanorings。

英文摘要:

In this paper, we report a new strategy for the fabrication of gold nanoring arrays via colloidal lithography and polymer-assisted self-assembly of gold nanoparticles (Au NPs). First, multi-segmented polymer nanorod arrays were fabricated via colloidal lithography. They were then used as templates for Au NP adsorption, which resulted in nanoparticles on the poly(4-vinyl pyridine) (P4VP) segments. Continuous gold nanorings were formed after electroless deposition of gold. The diameter, quantity, and spacing of the gold nanorings could be tuned. Three dimensional coaxial gold nanorings with varying diameters could be fabricated on a polymer nanorod by modifying the etch parameters. The nanorings exhibited optical plasmonic resonances at theoretically predicted wavelengths. In addition, the polymer-assisted gold nanorings were released from the substrate to generate a high yield of flee-standing nanorings. This simple, versatile method was also used to prepare nanorings from other metals such as palladium.
