摘要： A method for producing a conversion element comprising the following steps is described: providing a conversion layer having a matrix, in which phosphor particles are brought in, the phosphor particles comprising a host lattice having activator ions and being concentrated in a enrichment zone, providing a compensation layer having the matrix, in which compensation particles are brought in, which comprise the host lattice and are concentrated in a enrichment zone, and joining the conversion layer and the compensation layer in such a way that the enrichment zone of the conversion layer and the enrichment zone of the compensation layer are arranged symmetrically to one another with respect to a symmetry plane of the conversion element. A conversion element and a component are also specified.
