短波红外有机光探测材料的发展OA北大核心CSTPCD

The technology of short-wave infrared photodetection has achieved important applications in military defense,industrial manufacturing,medical diagnosis and other fields,but the high price limits its popularization and application scenarios.Development of short-wave infrared photodetection based on new photosensitive materials is considered to be the key to the large-scale application of this technology.Organic photodetectors have significant advantages in terms of low cost and flexibility,and are developing rapidly in the field of short-wave infrared photodetection.It is expected to be a complementary technology to InGaAs and quantum dots based ones,with the ability to achieve large-scale applications on the low-cost demand side in the field of Internet of Things and artificial intelligence economy.In this paper,we first introduce the basic working principles and performance parameters of organic photodetectors,followed by the reviewing of short-wave infrared photodetection polymers and small molecules,and finally the applications of organic short-wave infrared photodetectors are summarized.
