Abstract

The invention relates, inter alia, to an arrangement (10) for generating electromagnetic radiation, wherein the arrangement comprises inorganic semiconductor material and organic material (130), characterized by a semiconductor cylinder (30, 40) composed of inorganic semiconductor material and a charge carrier injection zone (50) situated in the semiconductor cylinder, wherein the charge carrier injection zone adjoins the lateral surface (110) of the semiconductor cylinder, the organic material (130) is suitable for emitting electromagnetic radiation in the case of a charge carrier recombination, and the organic material bears indirectly or directly on that section of the lateral surface of the semiconductor cylinder which is adjoined by the charge carrier injection zone and electron-hole pairs from the charge carrier injection zone of the semiconductor cylinder can enter into the organic material, and excite there the emission of electromagnetic radiation by recombination.
