Abstract
A method for producing an output coupling element and an output coupling element are disclosed. In an embodiment a method includes producing a suspension having quantum dots in a suspension medium, wherein each quantum dot comprises a core having a semiconductor material, directly applying the suspension onto a surface of an optoelectronic component and/or onto a surface of a carrier and removing the suspension medium for producing the output coupling element, wherein the output coupling element is matrix-free and transparent to radiation of a red range and/or a IR range.
