Abstract

Embodiments of the present invention are directed a β-SiAlON:Eu²⁺ based green emitting phosphor having the formula Eu_x(A1)_6−z(A2)_zO_yN_8−z(A3)_2(x+z−y), where 0x(A1)_6−z(A2)_zO_yN_8−z(A3)_2(x+z−y)have the same structure as β-Si₃N₄. Both elements A1 and A2 reside on Si sites, and both O and N occupy the nitrogen sites of the β-Si₃N₄crystal structure. A molar quantity (z−y) of the A3⁻ anion (defined as a halogen) reside on nitrogen sites.
