Abstract

A method for producing an optoelectronic device and an optoelectronic device is disclosed. According to at least one embodiment, an optoelectronic device is provided, which comprises a housing, a radiation-emitting or radiation-receiving semiconductor chip which is arranged in the housing, and an optical element which is arranged in a beam path of the device. The optical element comprises an amphiphilic block copolymer which contains polysiloxane as a hydrophobic polymer and a hydrophilic polymer cross-linked therewith. The optical element further comprises thermally conductive nanoparticles which are distributed in the amphiphilic block copolymer and comprise a material which is selected from the group comprising a metal, a metal oxide, a metal hydroxide and a combination thereof.
