The invention relates to a method for producing a conversion element (100) for an optoelectronic component (110) having the following steps: A) providing an acidic medium (1) with a pH value of less than 2, B) adding a conversion material (2) into the acidic medium (1), C) adding a silicate solution (3) with a viscosity of 2 to 10000 P to the mixture produced in step B) such that the pH value during the addition process in step C) is less than 2, wherein a precipitation (4) is obtained which comprises the conversion material (2) and silicon dioxide (41) as the matrix material, D) separating the precipitation (4), E) washing the precipitation (4) using a washing medium (6), said washing medium (6) having a pH value of less than 2, and F) curing the precipitation (4) in order to produce the conversion element (100). |
