    摘要： The invention relates to compounds comprising an anionic scaffold structure, dopants and cations, in which a. the anionic scaffold structure features coordination tetrahedra GL
    4 , 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 selected from the alkaline earth metals, with the proviso that strontium and barium together make up less than 75 atom% of the cations; c. dopant present comprises 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 these compounds, and to their use as conversion phosphors.
