Fig. 2From: Giant Tunable Circular Dichroism of Large-Area Extrinsic Chiral Metal Nanocrescent Arraysa, d Schematic of the lattice where the mirror axis of nanocrescents is oriented towards the [0, − 1] and [2, 1] crystal axis, respectively (the blocks represent the crystal cell); b, c extinction spectrums recorded by employing an incident light with left and right circular polarization, respectively. The mirror axis of nanocrescents is directed towards the [0, − 1] direction of the crystal lattice; e, f extinction spectrums recorded by employing an incident light with left and right circular polarization, respectively. The mirror axis of nanocrescents is directed towards the [2, 1] direction of the crystal latticeBack to article page
