Abstract
A device for converting the wavelength of electromagnetic radiation is disclosed. In an embodiment the device includes a carrier, a conversion layer configured to at least partly convert a wavelength of the electromagnetic radiation and an intermediate layer, wherein the conversion layer is connected to the carrier via the intermediate layer, and wherein the intermediate layer, at least in partial regions, includes a solid layer and a connection layer.
