Abstract
An epitaxial conversion element, a method for producing an epitaxial conversion element, a radiation emitting RGB unit and a method for producing a radiation emitting RGB unit are disclosed. In an embodiment an epitaxial conversion element includes a green converting epitaxial layer configured to convert electromagnetic radiation from a blue spectral range into electromagnetic radiation of a green spectral range and a red converting epitaxial layer configured to convert electromagnetic radiation from the blue spectral range into electromagnetic radiation of a red spectral range, wherein the green converting epitaxial layer and the red converting epitaxial layer are based on a phosphide compound semiconductor material, and wherein the green converting epitaxial layer and the red converting epitaxial layer are in different main extension planes which are parallel to each other.
