摘要: We demonstrate highly sensitive polymer photodetectors (OPDs) with spectral response extending from the ultraviolet to the near-infrared (NIR) region (similar to 1200 nm). After doping two NIR dopants, high external quantum efficiencies (similar to 5500%) and high responsivities (23.0 A/W) are achieved under a low reverse bias (-3.7 V). The high gains could be attributed to unbalanced carrier transport in the photoactive layer arising from the electron traps at the NIR dopants. This approach allows the ready preparation of OPDs exhibiting broad spectral responses and high quantum efficiencies simultaneously. (C) 2012 American Institute of Physics. [doi:10.1063/1.3675573]
