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.

Abstract: Wavelength converters including coarse particles/grains of a red nitride phosphor are disclosed. In some embodiments the red nitride phosphor is a (Ca,Sr,Ba)2Si5N8:Eu phosphor with a D50 grain size or a D50 particle size that is ≥5 microns. The red nitride phosphor may be encapsulated within an organic matrix or present in an inorganic matrix. In the latter case, the inorganic matrix may include fine grains with a D50 grain size
