A luminophore having the general empirical formula X′A′(AlA′)O:E′ that crystallizes in a tetragonal crystal system.

Yellow luminophore and light source

A phosphor may have the general formula EAADON:RE. EA may be selected from the group of divalent elements. A may be selected from the group of monovalent, divalent or trivalent elements. D may be selected from the group of trivalent or tetravalent elements. RE may be an activator element. 0&#x2264;x&#x2264;8, and &#x3b5;(4+4y+3z)=3(8&#x2212;x)+2x with the charge number y of element A, the charge number z of element D, and &#x3b5;=0.9-1.1.

Phosphor, method of producing a phosphor, and radiation emitting device

A luminophore may have the general empirical formula XAZO:E, where:

Luminescent substance and illuminating device

A method is provided for producing a pulverulent precursor material of the general formula M1M2(Si,Al)(O,N)or M1M2SiAlNhaving the method steps A) producing a pulverulent mixture of starting materials, B) calcining the mixture under a protective gas atmosphere and subsequent grinding, wherein in method step A) at least one nitride with a specific surface area of greater than 2 m/g is selected as starting material. A pulverulent precursor material and the use thereof are additionally provided.

Method for producing a powdered precursor material, powdered precursor material and use thereof

A method can be used for producing a powdery precursor material for an optoelectronic component having a first phase of the following general composition (CaZnMgSrBaX)SiN, wherein X is an activator that is selected from the group of the lanthanoids and wherein the following applies: 0&#x3c;a&#x3c;1 and 0&#x2266;b&#x2266;1 and 0&#x2266;c&#x2266; and 0&#x2266;d&#x2266;1 and 0&#x2266;e&#x2266;1. The method includes producing a powdery mixture of starting materials. The starting materials comprise ions of the aforementioned composition. At least silicon nitride having a specific surface area greater than or equal to 9 m/g is selected as a starting material and wherein the silicon nitride comprises alpha silicon nitride or is amorphous. The method also includes heat-treating the mixture under a protective gas atmosphere.
