我们利用胶体奈米孔微影技术制作出具有三维手性的大面积电浆子结构。通过改变蒸发过程中样品的极性旋转速度,我们可以制备出螺旋型斜坡纳米结构。光学性质显示在100至400 THz频率区域(750至3000 nm)的手光学共振,圆二色性值高达13%。我们的方法提供了一个简单的低成本的cm(2)大小的手性等离子体模板的手性光学应用,如立体化学对映体传感器的制造方法。
We manufacture large-area plasmonic structures featuring 3-dimensional chirality by colloidal nanohole lithography. By varying the polar rotating speed of the samples during gold evaporation, we can fabricate spiral-type ramp nanostructures. The optical properties show chiroptical resonances in the 100 to 400 THz frequency region (750 to 3000 nm), with circular dichroism values of up to 13%. Our method offers a simple low-cost manufacturing method of cm(2)-sized chiral plasmonic templates for chiroptical applications such as stereochemical enantiomer sensors.
