Devices for emitting and/or receiving electromagnetic radiation, and method for providing same

A device for emitting or detecting electromagnetic radiation, comprising:

• a first electrode and a second electrode;
• at least one electrically conductive nanostructure which connects the first electrode and the second electrode to each other and is configured to transport electrons and holes from the first and the second electrode or to the first and the second electrode;
• and
• at least one nanoscopic material structure arranged at a circumferential surface of the electrically conductive nanostructure, configured to absorb electrons and holes and emit the electromagnetic radiation with recombination of electrons absorbed and holes absorbed or to absorb electromagnetic radiation and emit electrons and holes based on the electromagnetic radiation absorbed;
• wherein
• an end of the electrically conductive nanostructure arranged at the first or the second electrode is surrounded at least partly by the first or second electrode along a region of the circumferential surface in order to provide electrical contact between the first or second electrode and the electrically conductive nanostructure,
• a control electrode element arranged to be adjacent to the electrically conductive nanostructure and configured to influence, when applying an electric voltage to the control electrode element by means of an electric field generated, an energy level of holes or electrons in the electrically conductive nanostructure;
• and
• wherein the device is implemented such that at least one of:
• the control electrode element is adjacent to the first electrode and additionally comprises at least another control electrode element arranged to be adjacent to the second electrode and configured to influence, when applying an electric voltage to the further control electrode element by means of an electric field generated, an energy level of holes or electrons in the electrically conductive nanostructure;
• the control electrode element is arranged between a substrate and the first electrode;
• the first electrode is arranged between the control electrode element and a substrate;
• and
• the control electrode element is arranged offset in a lateral direction perpendicularly to a connective axis between the first electrode and the second electrode;
• and
• wherein the device further comprises an electroluminescent or phosphorescent or fluorescent light converter molecule arranged at a circumferential surface of the electrically conductive nanostructure and configured to receive at least partly the electromagnetic radiation at the first wavelength and emit electromagnetic radiation at a second wavelength based on a fluorescence or phosphorescence.
