1. A phosphor with the general formula EA2A4D3OxN8-x:RE, wherein:
EA is selected from the group of divalent elements;
A is selected from the group consisting of monovalent elements, divalent elements, or trivalent elements;
D is selected from the group consisting of trivalent elements or tetravalent elements;
RE is 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.
