Ceramic conversion element, semiconductor chip comprising a ceramic conversion element and method for producing a ceramic conversion element

摘要

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.

1. A ceramic conversion element comprising:
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, a carrier layer transmissive to radiation in the first wavelength range and/or radiation in the second wavelength range, and an inhibitor layer having a thickness which is not greater than 5 μm arranged between the active layer and the carrier layer, said inhibitor layer reducing diffusion of activator ions from the active layer into the carrier layer, wherein the active layer, the carrier layer and the inhibitor layer are formed from a ceramic material.
