Abstract

The invention relates to a luminescent substance consisting of a doped host lattice which absorbs at least one part of exciting radiation when it is excited by a high-energy radiation, thereby releasing an energy-poor emission radiation. The host lattice is embodied in the form of a carbidonitridosilicate-based compound. An illuminant which is used for producing white light and comprises a light emitting element and said luminescent substance are also disclosed.
