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 and a conversion element arranged directly downstream of the main radiation exit surface, wherein the conversion element is substrate-free and includes 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 inorganic sol-gel material selected from the following group consisting of water glass, metal phosphate, aluminum phosphate, modified monoaluminum phosphate, monoaluminum phosphate, alkoxytetramethoxysilane, tetraethylorthosilicate, methyltrimethoxysilane, methyltriethoxysilane, titanium alkoxide, silica sol, metal alkoxide, metal oxane, metal alkoxane, metal oxide, metal silicates, metal sulfates, and tungstates, and wherein the condensed sol-gel material has a proportion between 10 and 70 vol % in the first layer.
