Abstract

A phosphor may have the general formula EA2A4D3OxN8-x: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≤x≤8, and ε(4+4y+3z)=3(8−x)+2x with the charge number y of element A, the charge number z of element D, and ε=0.9-1.1.
