摘要

柔性和宽频带光电探测器由于在许多领域的广泛应用而引起了人们的广泛关注。本文采用水热法合成了mn掺杂ZnSe微球，并采用简单的全干摩擦技术在纸基上制备了基于该微球的光电探测器。Mn元素以取代形式完全融入ZnSe晶格中，当Mn掺杂摩尔比为2%时，宽区域的电子密度和光吸光度显著增强。基于2-MnZnSe的光电探测器由于具有较高的光生载流子和电荷转移速率，在紫外和可见光下表现出最佳的响应性和探测性。本研究为柔性、宽带、高性能、低成本光电探测器的研制提供了一条有效途径。

Flexible and broadband photodetector based on Mn-doped ZnSe on paper substrate

Flexible and broadband photodetectors on paper substrates have drawn considerable attention for their extensive applications in many fields. In this work, Mn-doped ZnSe microspheres were synthesized by the hydrothermal method, and the photodetectors based on them were fabricated on paper substrates using a simple all-dry rubbing technique. Mn element is totally incorporated into the ZnSe lattice in the substitutional form, and the electron-density and light absorbance in wide region are enhanced significantly when the molar ratio of Mn-dopant concentration is 2 %. The fabricated photodetector based on 2-MnZnSe shows the best responsivity and detectivity under UV and visible light illuminations due to the relatively high photogenerated carriers and charge transfer rate. This study offers an effective route in the field of flexible and broadband photodetector with high performance and low cost.

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
