Abstract
A method of manufacturing a conversion element is disclosed. A precursor material is selected from one or more of lutetium, aluminum and a rare-earth element. The precursor material is mixed with a binder and a solvent to obtain a slurry. A green body is formed from the slurry and the green body is sintered to obtain the conversion element. The sintering is performed at a temperature of more than 1720° C.
