Abstract

An optoelectronic component that emits electromagnetic radiation from a radiation exit surface of the optoelectronic component includes a radiation-emitting semiconductor chip that produces electromagnetic radiation, and a marker element applied to the radiation exit surface of the optoelectronic component, the marker element including a dye substance that can be removed from the radiation exit surface using a solvent and/or is permeable to the electromagnetic radiation of the optoelectronic component, wherein the dye substance includes a resin into which fluorescent particles are introduced that convert electromagnetic radiation of a first wavelength range into electromagnetic radiation of a second wavelength range, the first wavelength range and the second wavelength range being within the ultraviolet spectral range.
