Abstract
A ceramic conversion element includes an active ceramic layer that converts electromagnetic radiation in a first wavelength range into electromagnetic radiation in a second wavelength range, which is different from the first wavelength range, and a carrier layer transmissive to radiation in the first wavelength range and/or radiation in the second wavelength range, wherein an inhibitor layer is arranged between the active layer and the carrier layer, the inhibitor layer reducing diffusion of activator ions from the active layer into the carrier layer.
