Abstract

The invention describes a device for emitting or detecting electromagnetic radiation. The device has a first and a second electrode which are connected to each other via an electrically conductive nanostructure. The electrically conductive nanostructure is configured to receive electrons and holes from the first and second electrode or transport same to the first and second electrode. In addition, the device has a radiation molecule arranged at a circumferential surface of the electrically conductive nanostructure. The radiation molecule is configured to absorb electrons and holes or electromagnetic radiation and emit the electromagnetic radiation with recombination of electrons absorbed and holes absorbed, or emit electrons and holes based on the electromagnetic radiation absorbed. The electrically conductive nanostructure is, in the region of a circumferential surface, surrounded at least partly by the first or second electrode at an end arranged at the first or second electrode in order to provide electrical contact of the first or second electrode and the electrically conductive nanostructure.
