Photodetector as key important element of optoelectronics is important in both photon detection and solar energy conversion. Under the support of NSFC key project,NSFC-NSF international collaboration project and CMS innovation project of ICCAS,the researchers in CAS Key Laboratory of Molecular nanostructure and nanotechnology and Key Laboratory of Organic Solids made a series of progresses in photodetectors based on metal selenide nanomaterials(J. A single nanowire deposited between two electrodes produced a low current(40 pA)in the dark,and a current up to 50 times higher(2000 pA)upon visible light irradiation. The device showed distinct“ON”(0.15 pA)and“OFF”(17 pA)states with fast and reversible switching responding to outside illumination.
