Abstract: An optoelectronic arrangement having a radiation conversion element and a method for producing a radiation conversion element are disclosed. In an embodiment, an optoelectronic arrangement includes a semiconductor chip having an active region configured to generate radiation, a radiation conversion element arranged downstream of the semiconductor chip in an emission direction and a reflective polarization element arranged downstream of the radiation conversion element in the emission direction. The radiation conversion element has a plurality of conversion elements, each of which has an axis of symmetry, the spatial orientation of the axes of symmetry has a preferred direction and a radiation emitted by the radiation conversion element has a preferred polarization. The reflective polarization element largely allows radiation with the preferred polarization to pass through and largely reflects radiation polarized perpendicularly to the preferred polarization.
