Abstract

An optoelectronic component comprises an organic layer sequence (1), which emits an electromagnetic radiation (15) having a first wavelength spectrum during operation, and also a dielectric layer sequence (2) and a wavelength conversion region (3) in the beam path of the electromagnetic radiation (15) emitted by the organic layer sequence (1). The wavelength conversion region (3) is configured to convert at least partially electromagnetic radiation having the first wavelength spectrum into an electromagnetic radiation (16) having a second wavelength spectrum. The dielectric layer sequence (2) is arranged in the beam path of the electromagnetic radiation (15) emitted by the organic layer sequence between the organic layer sequence (1) and the wavelength conversion region (3) and is at least partially opaque to an electromagnetic radiation having a third wavelength spectrum, which corresponds to at least one part of the second wavelength spectrum.
