A device that can produce electroluminescence from infrared to ultraviolet wavelengths

Electroluminescence (EL), electrically produced luminescence, is crucial to the operation of many electronic devices that are designed to emit light. EL can theoretically be achieved in devices with a variety of structures and made of different materials. However, to be electroluminescent, these devices need to have a number of core features that allow them to support specific light-emitting materials.
