摘要

通过热旋镀方法，在柔性 PET 衬底上制造出了铯铋 3I10 薄膜光电探测器。所制备的无毒光电探测器表现出卓越的光电性能，Ilight/Idark 比值为 1.8 × 103，响应率为 18.3 mA/W，探测率为 2.95 × 108 Jones。它还显示出宽光谱响应，并在 506 次光切换周期和 1000 次弯曲周期后保持性能稳定。该装置的动态成像能力得到了进一步验证，显示了其在各种应用中的潜力。这项工作开创了铯铋3I10包晶薄膜在柔性光电探测器中的应用，为下一代光电器件提供了一种绿色、稳定和高性能的解决方案。

Lead-Free CsBi3I10 Thin-Film flexible photodetectors with enhanced performance for broad spectral response

By employing a hot spin-coating method, CsBi₃I₁₀ thin-film photodetector was fabricated onto flexible PET substrate. The resulting nontoxic photodetector demonstrated exceptional optoelectronic performance, featuring an I_light/I_dark ratio of 1.8 × 10³, a responsivity of 18.3 mA/W and a detectivity of 2.95 × 10⁸ Jones. It also showed a broad spectral response and maintained consistent performance after 506 light switching cycles and 1000 bending cycles. The dynamic imaging capability of the device was further validated, illustrating its potential for diverse applications. This work pioneers the application of CsBi₃I₁₀ perovskite thin-film in flexible photodetectors, offering a green, stable and high-performance solution for next-generation optoelectronic devices.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
