中文摘要:光电探测器在遥感,夜视,侦察,医学成像,热成像和化学检测等方面的应用十分广泛,而光电探测材料的结构及性能直接影响光电探测器的性能。近年来碳纳米管由于其独特的光学和电学性能迅速成长为光电探测中不可或缺的材料。前期研究主要集中在基于单根碳纳米管的光电器件,但未来的应用场景中必然是以碳纳米管薄膜为基础的,因而围绕制备大面积、高密度、高取向、高均匀度碳纳米管薄膜,并以此为基础制备光电探测器件成为了近期碳纳米管领域的研究热点。本文围绕近年来碳纳米管薄膜的制备及其在光电探测器件的应用等方面的进展,分别进行了详尽的介绍和讨论,并展望了碳纳米管薄膜光电探测器的发展趋势。

Progress in carbon nanotube films based photodetectors
Abstract:Photodetectors play a key role in various demanding applications, such as remote sensing, night vision, reconnaissance, medical imaging, thermal imaging and chemical detection, etc. And the structures and features of the photodetecting materials directly affect the performance of the photodetectors. In recent years, carbon nanotubes (CNT) have rapidly grown into the alternative materials in photodetection due to their unique optical and electrical properties. While the early researches were mainly focused on photodetectors based on individual carbon nanotubes, potential applications require carbon nanotube thin films as the detecting layers to maximize the photo absorption ability and the detective efficiency. Therefore, the preparation of large-area, high-density, high-orientation, and high-uniformity carbon nanotube thin films, and the fabrication of the photodetectors based on these thin films, have attracted great research interest in the field of CNTs. Herein we elaborate the development of the preparation methods of CNT thin films as well as the recent progress in the CNT-based photodetectors with a discussion on its development tendency in the near future.
