Abstract

The invention relates to an optoelectronic device (101), comprising: a semiconductor layer sequence (103) comprising an emitter layer (105) for emitting electromagnetic radiation, a converter (113) for converting electromagnetic radiation with a first wavelength into an electromagnetic radiation with a second wavelength which differs from the first wavelength, a scattering body (109) for scattering at least a part of the electromagnetic radiation emitted by the emitter layer (105) in the direction of the converter (113) in order to convert at least a part of the emitted electromagnetic radiation, wherein the scattering body (109) comprises a positive, temperature-dependent scattering cross-section and so, as the temperature increases, scattering of the electromagnetic radiation in the scattering body (109) in the direction of the converter can be increased. The invention also relates to a scattering body (109).
