  • Publication number: 20160152891
    Abstract: Compounds containing an anionic scaffold structure, dopants and cations, in which a. the anionic scaffold structure features coordination tetrahedra GL4, where G stands for silicon, which may be partly replaced by C, Ge, B, Al or In, and L stands for N and O, with the proviso that N makes up at least 60 atom % of L; b. the cations are alkaline earth metals, with the proviso that strontium and barium together make up less than 75 atom % of the cations; c. dopant present trivalent cerium or a mixture of trivalent cerium and divalent europium; d. charge compensation of the cerium doping is accomplished i) through corresponding replacement of alkaline earth metal cations by alkali metal cations, and/or ii) by a corresponding increase in the nitrogen content, and/or iii) by a corresponding reduction in the cations; and to processes for preparing, and to their use as conversion phosphors.
