Highly Efficient Top‐Emitting Infrared‐to‐Visible Up‐Conversion Device Enabled by Microcavity Effect

Infrared (IR)‐to‐visible up‐conversion device allows a low‐cost, pixel‐free IR imaging over the conventional expensive compound semiconductor‐based IR image sensors. However, the external quantum efficiency has been low due to the integration of an IR photodetector and a light‐emitting diode (LED)....
