单晶纳米线托克斯探测器制备及测试数据集

偏振光在生产生活中起到了至关重要的作用，对偏振光的处理和检测不仅强化了传统的应用，如光学成像、全息摄影、椭圆光度测量和光谱学等，而且也加速了量子计算和通信等新兴领域的发展。为了加快光电探测器向集成应用方向发展，材料设计和结构工程已经被广泛应用到偏振光检测中。通过开发手性超表面、光的自旋-轨道耦合和具有内在手性的有机分子器件，能够控制带有不同自旋角动量光子的吸收或空间分布，已经实现圆形偏振光的直接探测。同时，通过开发具有各向异性介电场的材料或纳米结构，其中吸收系数取决于光的电振荡与材料轴之间的夹角，线性偏振光的检测也被证实是可行的。虽然结合不同光子结构的多个探测器能够确定所有的光学偏振状态，但是，全斯托克斯探测在单个器件中仍然是难以实现的。本数据集中，利用毛细液桥诱导的液相加工方法，成功制备了结晶取向单一的手性二维钙钛矿纳米线阵列器件，有效地实现了任意偏振光的探测，很好地弥补了上述缺憾。该方法通过控制毛细液流的定向输运实现了晶体的限域成核生长过程，从而制备了有序排列和严格取向的单晶纳米线阵列。在分子尺度，插层手性胺分子赋予探测器圆偏光探测的能力，最大各向异性因子为0.15；在纳米尺度，1D钙钛矿纳米线结构赋予其线偏振光探测功能，最大偏振比为1.6。协同优异的线偏振光和圆偏振光探测性能，研究人员制备了任意偏振光探测的全斯托克斯探测器，加速了小型化，集成化的光电子器件发展。沿着纳米线方向，单晶性和严格取向的纳米线阵列允许有效的面内载流子传输，实现了47.1 A W-1的响应度和1.24 × 1013 Jones的检测率。同时，这种小尺寸和高性能的斯托克斯探测器也实现了高精度偏振成像的功能。本数据集是2018-2021年在中国科学院理化技术研究所仿生材料与界面科学院重点实验室完成的，主要记录了手性分子与器件的示意图、圆二色谱、阵列X射线衍射、透射电镜照片、扫描电镜照片、掠入射广角X射线散射数据、偏振光探测器件数据等。

Polarized light plays a crucial role in both industrial production and daily life. The processing and detection of polarized light not only enhance traditional applications such as optical imaging, holography, ellipsometry, and spectroscopy, but also accelerate the development of emerging fields including quantum computing and communication. To speed up the development of photodetectors toward integrated applications, material design and structural engineering have been widely applied in polarized light detection. By developing chiral metasurfaces, spin-orbit coupling of light, and organic molecular devices with intrinsic chirality, which enable control over the absorption or spatial distribution of photons with different spin angular momenta, direct detection of circularly polarized light has been realized. Meanwhile, by developing materials or nanostructures with anisotropic dielectric fields, where the absorption coefficient depends on the angle between the electrical oscillation of light and the material axes, the detection of linearly polarized light has also been proven feasible. Although multiple detectors combined with different photonic structures can identify all optical polarization states, full Stokes polarization detection remains difficult to achieve in a single device.

In this dataset, we successfully fabricated single-crystallographically oriented chiral two-dimensional (2D) perovskite nanowire array devices via a capillary liquid bridge-induced liquid-phase processing method, which enabled efficient detection of arbitrary polarized light and well addressed the aforementioned limitations. This method achieves confined nucleation and growth of crystals by controlling the directional transport of capillary liquid flow, thereby preparing ordered and strictly oriented single-crystalline nanowire arrays. At the molecular scale, intercalated chiral amine molecules endow the detector with the capability of circularly polarized light detection, with a maximum anisotropy factor of 0.15; at the nanoscale, the 1D perovskite nanowire structure enables linearly polarized light detection, with a maximum polarization ratio of 1.6. Leveraging the excellent synergistic performance of linearly and circularly polarized light detection, researchers fabricated a full Stokes polarization detector capable of detecting arbitrary polarized light, accelerating the development of miniaturized and integrated optoelectronic devices.

Along the direction of the nanowires, the single-crystalline and strictly oriented nanowire arrays allow efficient in-plane carrier transport, achieving a responsivity of 47.1 A W⁻¹ and a detectivity of 1.24 × 10¹³ Jones. Meanwhile, this compact and high-performance Stokes detector also realizes high-precision polarization imaging.

This dataset was completed between 2018 and 2021 at the Key Laboratory of Bio-inspired Materials and Interfaces, Technical Institute of Physics and Chemistry, Chinese Academy of Sciences. It primarily records schematic diagrams of chiral molecules and devices, circular dichroism (CD) spectra, array X-ray diffraction patterns, transmission electron microscopy images, scanning electron microscopy images, grazing-incidence wide-angle X-ray scattering data, and polarized light detection device data, among other related contents.
