Abstract

A method for producing a structured wavelength conversion layer is disclosed. In an embodiment the method comprises the following steps: - providing a first wavelength conversion layer with wavelength converting properties such that electromagnetic radiation of a first wavelength range is converted into electromagnetic radiation of a second wavelength range, - structuring of the first wavelength conversion layer into first regions and second regions, wherein the wavelength converting properties of the wavelength conversion layer are impaired or removed in the first regions after the structuring. Furthermore, an optoelectronic device with a structured wavelength conversion layer is specified.
