Abstract
A method for producing a conversion element is disclosed. In an embodiment, the method includes providing an acidic medium having a pH value of less than 2, adding a conversion material into the acidic medium thereby forming a mixture and adding a silicate solution having a viscosity between 2 to 10 000 poize inclusive to the mixture such that the pH value during the addition of the silicate solution is smaller than 2. The method further includes obtaining a precipitate which contains the conversion material and silicon dioxide as a matrix material, separating the precipitate, washing the precipitate with a washing medium, wherein the washing medium has a pH value of less than 2; and hardening the precipitate thereby forming the conversion element.
