摘要
The present invention relates to a method of manufacturing a powdered precursor material for an optoelectronic device (100) having a first phase of the following general chemical composition (Ca 1-abcde Zn d Mg e Sr c Ba b X a ) 2 Si 5 N 8 Wherein X is an activator selected from Lanthanon elements, where 0 a 1 and 0 b 1 and 0 & 1, and A) preparing a powdered mixture of educts, wherein the extracts contain ions of the chemical composition described above and the extract has a specific surface area of greater than or equal to 9 m 2 / g Wherein the silicon nitride comprises alpha-silicon nitride or has amorphous, and B) annealing the mixture under a protective gas atmosphere.
