Abstract:
A ceramic conversion element includes a first ceramic layer having a first luminescent material, which transforms electromagnetic radiation of a first wavelength range into electromagnetic radiation of a second wavelength range. A second ceramic layer includes a second luminescent material, which transforms electromagnetic radiation of the first wavelength range into electromagnetic radiation of a third wavelength range. The first luminescent material and the second luminescent material are based on at least one inorganic compound containing oxygen and are different from one another. An optoelectronic component with a ceramic conversion element and a method for producing a ceramic conversion element are also specified.
