Abstract: An organic photodetector detects infrared radiation, particularly radiation within the spectral region of over 1100 nm, the so-called imager region. Contrary to the currently known photodetectors, such as the Bolometer, II-VI semiconductor, and quantum well detectors, the photodetector contains semiconducting nano-particles for shifting the range of detection, requires no technical and cost-intensive effort in the production thereof, and may be constructed of flexible substrates by simple printing methods.
