Claim 0:
1. A converter system comprising:
a first material, which comprises an emitting material, adapted to emit a color of interest, wherein the first material is essentially free of a sensitizer material; and
a second sensitizer material, which is essentially free of the first material and is excitable in the wavelength range of interest and its emission spectrum overlaps at least partly with one or more excitation bands of the first material,
wherein the emitting material of the first material comprises one or more of the ions of the group comprising Eu3+, Tb3+ and Mn4+, and
wherein the second sensitizer material comprises one or more ions selected out of the group Eu2+, Pb2+, Bi3+ and Ce3+,
wherein the emitting material and the second sensitizer material are disposed in different host lattices, and
wherein the converter system is adapted to radiatively excite the second sensitizer material.
