Abstract

An optoelectronic component and a method for producing an optoelectronic component are disclosed. In an embodiment an optoelectronic component includes a semiconductor layer sequence having an active region configured to emit radiation at least via a main radiation exit surface during operation and a self-supporting conversion element arranged in a beam path of the semiconductor layer sequence, wherein the self-supporting conversion element includes a substrate and subsequently a first layer, wherein the first layer includes at least one conversion material embedded in a matrix material, wherein the matrix material includes at least one condensed sol-gel material, wherein the condensed sol-gel material has a proportion between 10 and 70 vol % in the first layer, and wherein the substrate is free of the sol-gel material and the conversion material and mechanically stabilizes the first layer.
