Method for producing a powdery precursor material, powdery precursor material, and use of said powdery precursor material
The invention relates to a method for producing a powdery precursor material for an optoelectronic component (100) having a first phase of the following general composition (Ca1-a-b-c-d-eZndMgeSrcBabXa)2Si5N8, wherein X is an activator that is selected from the group of the lanthanoids, wherein the following applies: 0 < a < 1 and 0 <= b <= 1 and 0 <= c <= 1 and 0 <= d <= 1 and 0 <= e <= 1, comprising the following steps: A) producing a powdery mixture of starting materials, wherein the starting materials comprise ions of the aforementioned composition, wherein at least silicon nitride having a specific surface area greater than or equal to 9 m/g is selected as a starting material, wherein the silicon nitride comprises alpha silicon nitride or is amorphous, and B) heat-treating the mixture under a protective gas atmosphere.
