Abstract

An organic light-emitting component (100) is specified, which comprises a carrier (1) and an organic layering sequence (2) arranged on the carrier (1). The organic layering sequence (2) comprises at least two organic layers, wherein at least one of the organic layers is designed as an emitting layer (23). The emitting layer (23) emits light (200) of a first wavelength range, which has an intensity maximum at a first wavelength. Further, the organic light-emitting component (100) comprises an anode (3) and a cathode (4) which provide the electrical contacting of the organic layering sequence (2). Further, the organic light-emitting component (100) has at least one nanoparticle layer (20), wherein one nanoparticle layer (20) is an organic layer of the organic layering sequence (2) provided with first nanoparticles (5). The first nanoparticles (5) have a refractive index (nN) that is smaller than at least one refractive index of an organic material of one of the organic layers. Further, at least one nanoparticle layer (20) is not in direct contact with the anode (3). In addition, the first nanoparticles (5) have a diameter that is smaller than one-fourth of the first wavelength at whi…
