Randomized trial demonstrates controllable near-infrared circularly polarized light switching in metal clusters, suggesting a new approach for efficient CPL materials.
Key Points
This research aims to investigate how helical photonic confinement allows for controllable switching of near-infrared circularly polarized light (NIR-CPL).
Studied assembly-disassembly of metal clusters within helical nanochannels.
Analyzed the mechanism of CPL enhancement through chiral photonic propagation modulation.
CPL enhancement due to chiral photonic propagation modulation rather than intrinsic emitter chirality is confirmed.
Heinical confinement enables efficient switching and handedness inversion of NIR-CPL.
The method can be extended to multicolor metal clusters for improved CPL materials.
