Abstract

This work investigates a soft host for liquid crystal lasers, formed by blending intrinsic chiral carbon nanotubes (c-CNTs) into cholesteric liquid crystals (CLCs). The emission intensity of the doped luminescent dye (DCM) exhibited pronounced photonic bandgap dependence. Furthermore, blending c-CNTs significantly enhanced the DCM emission intensity and improved its long-term stability, attributed to multi-domain scattering arising from internal refractive index variations. These findings provide insights into the tunability of liquid crystal lasers and highlight the potential of c-CNTs blending CLC-hosts for applications in photonics, imaging, and medicine.

本征手性碳纳米管混合胆甾型液晶基质中DCM的可调谐和长时间发射。

本研究研究了一种用于液晶激光器的软宿主，该宿主通过将本征性碳纳米管（c-CNTs）混合到胆甾型液晶（CLCs）中形成。掺杂发光染料（DCM）的发射强度表现出明显的光子带隙依赖性。此外，由于内部折射率变化引起的多域散射，共混c-CNTs显著增强了DCM的发射强度并改善了其长期稳定性。这些发现为液晶激光器的可调性提供了见解，并突出了c-CNTs混合clc -宿主在光子学、成像和医学应用中的潜力。

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
