FIELD: physics.
SUBSTANCE: illumination system having a radiation source and a composite monolithic ceramic luminescence converter having a composite luminescent material containing at least one first phosphor and at least one second phosphor, where the first phosphor is a green-emitting phosphor and the second phosphor is a red-emitting phosphor, and where the green phosphor is a europium(II)-doped alkaline earth oxonitridosilicate of general formula AeSi2N2O2:Eu, and the red phosphor is a europium(II)-doped alkaline earth nitridosilicate of general formula Ae2Si5N8:Eu.
EFFECT: improved light mixing and chromaticity control of the emitted light mixture.
