Abstract

A method of producing an optoelectronic component including a conversion element includes: A) providing a layer sequence having an active layer, wherein the active layer is configured to emit electromagnetic primary radiation; B) providing quantum dots, wherein the quantum dots are functionalized with an organic group and/or the quantum dots dissolved or dispersed in a first solvent and/or are present as a powder; C*) providing a mixture including a precursor of an inorganic matrix material and of a second solvent; D) mixing the mixture obtained in step C*) with the quantum dots of step B); E) drying the mixture; and F) sintering the mixture to form the conversion element.
