Abstract: A method for producing an output coupling element and an optoelectronic component are disclosed. In an embodiment, a method includes providing an inorganic dielectric element with a surface in a chamber, wherein the inorganic dielectric element rotates in the chamber during operation and providing a structuring agent comprising water and ozone and introducing the structuring agent into the chamber so that the structuring agent contacts the surface of the inorganic dielectric element and a roughening is produced in the surface, wherein the inorganic dielectric element comprises aluminum oxide.

Abstract: A method for producing an output coupling element and an optoelectronic component are disclosed. In an embodiment, a method includes providing an inorganic dielectric element with a surface in a chamber, wherein the inorganic dielectric element is rotatable in the chamber, providing a structuring agent comprising water and ozone and introducing the structuring agent into the chamber so that the structuring agent contacts the surface of the inorganic dielectric element thereby producing a roughening in the surface.
