| Abstract |
Natural materials behold innate handedness or chirality, for example, in the L or D forms of amino acids and twisted double helix of DNA molecules. However control of handedness in artificial materials is still challenging, especially for chiral nanomaterials. Chiral nanomaterials possess mirrored geometries that are lack of translation and rotation symmetry in 3-dimensional spaces in nanoscale. Therefore preparations of such chiral materials were only achieved via advanced lithography with high cost and complicated process via self-assembly of DNA molecules. Here we present a facile route to self-assemble 3D chiral nanostructures with controllable optical activity in the visible range without using any lithography or intrinsic chiral biomaterials. The chiral nanocomposite films with plasmonic nanoparticles can be reversibly deformed to have preferred absorptions of circularly polarized lights via modulation of in-plane axial strain. We believe that the artificial chiral nanomaterials have potential to be applied in advanced applications such as photoelectronic devices and metamaterials in optical devices. |
