1.IntroductionrnPhotodetectors are of great importance for a variety of industrial and scientific applications, such as in spectroscopy, solar energy harvesting, thermo-therapy, military detection, and a variety of biochemical sensors[1-5].Nowadays, relatively mature light detectors are mainly based on semiconducting materials including GaN, InGaAs and HgCdTe[6,7], and their light detection capability can reach 1011 Jones.However, most devices need to be cooled down to low working temperatures to achieve a high performance.In addition, these materials are usually not stable under strong illumination and not flexible[8,9], which greatly restricts the application range of fabricated photodetectors, especially in flexible and wearable devices.Therefore, the development of flexible, air-stable, room-temperature photodetectors is highly desired.
