Abstract:
The present invention relates to a process for the preparation of a europium-doped alkaline-earth metal siliconitride or silicooxynitride having increased emission efficiency. The present invention furthermore relates to europium-doped alkaline-earth metal siliconitrides or silicooxynitrides which are obtainable by the preparation process according to the invention, and to the use of the europium-doped alkaline-earth metal siliconitrides or silicooxynitrides according to the invention as conversion phosphors. The present invention furthermore also relates to a light-emitting device which comprises a europium-doped alkaline-earth metal siliconitride or silicooxynitride according to the invention.
