Abstract
Embodiments of the invention are directed to an improved device for sensing infrared (IR) radiation with upconversion to provide an output of electromagnetic radiation having a shorter wavelength than the incident IR radiation, such as visible light. The device comprises an anode, a hole blocking layer to separate an IR sensing layer from the anode, an organic light emitting layer that is separated from the anode by the IR sensing layer, and a cathode. The hole blocking layer assures that when a potential is applied between the anode and the cathode the organic light emitting layer generates electromagnetic radiation only when the IR sensing layer is irradiated with IR radiation.
