Photodetectors, methods for their preparation, and methods for detecting radiation using the same are described. The photodetector may comprise a first electrode, a light sensing layer, an electron blocking / tunneling layer and a second electrode. An infrared-to-visible upconversion device, a manufacturing method thereof, and a method of detecting radiation using the same are also described. The infrared-to-visible upconversion device may include a photodetector and an OLED coupled to the photodetector. |
