摘要： An organic photodetector for detecting infrared, visible and ultraviolet radiation is provided with a tunable spectral response to achieve a high responsivity at different design wavelengths. The organic photodetector comprises at least a substrate, a first electrode, a second electrode and at least one organic material, which is arranged between the first and the second electrodes, wherein a Schottky barrier is formed at the interface between the first electrode and the organic material and/or at the interface between the second electrode and the organic material. The tunability in the responsivity of the organic photodetector is achieved by structuring at least one electrode so that it comprises nano-apertures for exciting surface plasmon resonances.
