摘　　要：近红外及短波红外光探测器在热成像、夜视、农业视察、生物识别传感和遥感等相关领域具有重要的应用。然而目前大多数商用的红外光探测器需要额外的制冷设备辅助,并且器件不可弯折,很大程度上限制了它的应用。为了解决这些问题,近年来涌现了越来越多有关有机半导体的研究。有机半导体不仅具有可精细调控的带隙、高的吸光系数和机械柔性等优点,并且能够通过“卷对卷”工艺实现大面积制备并与柔性基底兼容。基于有机半导体的红外光探测器无需额外的制冷设备且具有无机红外光探测器所不具备的诸多特点,因而很有希望用于发展下一代红外光探测技术。本综述首先介绍了有机近红外及短波红外光探测光电晶体管、光电二极管器的基本原理,其次介绍了近年来兴起的有机半导体复合材料及其新颖的器件结构,接着总结了有机红外光探测器在电子眼、人工突触、以及可穿戴实时健康监测等应用的最新进展。最后,讨论了这一领域存在的挑战并对其未来发展进行了展望,以期促进该领域的进一步发展。Near and shortwave infrared organic photodetector(OPDs)is extremely significant for the application as thermal imaging,night vision,agricultural inspection,biometric sensors,remote sensing and related fields.However,most commercial infrared photodetectors generally require extra deep cooling equipment and are unable to bend,which limit their applications seriously.In order to overcome these challenges,more and more researches related with organic semiconductors(OSCs)emerge.OSCs with advantages including easy and elaborate tunability of optical properties,high optical absorption coefficient,and mechanical flexible,are able to fabricate over large areas with roll⁃to⁃roll processing and be compatible with flexible substrates.Infrared photodetectors based on OSCs attract more and more attention,which are free with extra deep cooling equipment and possess many advantages beyond inorganic infrared OPDs.They are deemed as attractive candidates for next generation infrared photodetectors.Recently,infrared OPDs have attracted more and more research attention.In this review,we first introduce the basic principles of organic phototransistors and photodiodes,and present development of organic complex materials and novel device configurations.Then we summarize state⁃of⁃the⁃art applications such as electronic eyes,artificial synapse and wearable devices for real⁃time health monitoring.Finally,we discuss challenges in this field and prospect future development.We believe that this review will promote the developments in the photodetector fields.
