Propagation of Polarized Optical Signal Through Gold Nanorods Blending Cholesteric Liquid Crystals

Description:

The incorporation of nanomaterials into cholesteric liquid crystals (CLCs) for helical templating not only effectively modulates the pitch of the CLCs but also provides a robust methodology for investigating the self-assembly characteristics of nanomaterials. In this study, an innovative blending method was employed to explore the helical assembly properties of gold nanorods (Au NRs) within a photo-tunable CLCs. The specific operation enabled the precise control of both the pitch of the CLCs and the helical self-assembly of Au NRs through the use of ultraviolet (UV) irradiation technology. It is notable that the system formed by this regulation not only exhibits excellent and stable reflective performance comparable to traditional CLCs but also possesses a unique ability to efficiently modulate the flux of incident light at near-infrared wavelengths. The synergistic regulation mechanism constructed by the helical assembly of Au NRs and the CLCs actively promotes the development of traditional liquid crystal display technology and paves the way for highly promising new avenues of research in the field of multi-layer information encryption.
