Abstract
Provided is a device for emitting electromagnetic radiation. The device includes a first electrode, a second electrode, and an exciton recombination layer extending from the first electrode to the second electrode. The device is configured to relocate a recombination zone in the exciton recombination layer by changing an electric field between the first electrode and the second electrode, or to emit electromagnetic radiation through a transparent substrate.
Claims15
A device for emitting electromagnetic radiation, comprising:
- a first electrode;
- a second electrode;
- and
- an exciton recombination layer extending from the first electrode to the second electrode;
- wherein the device is configured to relocate a recombination zone in the exciton recombination layer by changing an electric field between the first electrode and the second electrode.
A device for emitting electromagnetic radiation, comprising:
- a transparent substrate;
- a first electrode formed on the transparent substrate;
- a second electrode formed above the first electrode;
- and
- an exciton recombination layer between the first electrode to the second electrode;
- wherein the device is configured to emit the electromagnetic radiation through the transparent substrate.
A method of controlling properties of electromagnetic radiation, comprising deactivating a first optical antenna, of two, three or more optical antennas, and activating a second optical antenna, of the two, three or more optical antennas, by reversing a polarity of the first and second optical antennas which causes an exciton recombination zone in an exciton recombination layer extending from the first optical antenna to the second optical antenna to decouple from the first optical antenna and couple to the second optical antenna, wherein the first optical antenna emits electromagnetic radiation in a first spectrum and the second optical antenna emits electromagnetic radiation in a second spectrum which differs from the first spectrum and/or the first optical antenna and the second optical antenna lead to differences in directivity and/or polarization of the emitted electromagnetic radiation.
