<p>Embodiments of the present invention are directed a ß-SiA1ON:Eu2+ based green emitting phosphor having the formula Eux(Al)6_z(A2)zOyN8-z(A3)2(x+z-y), where 0 < z = 4.2; 0 = y = z; 0 < x = 0.1; A1 is Si, C, Ge, and/or Sn; A2 is A1, B, Ga, and/or In; A3 is F, C1, Br, and/or 1. The new set of compounds described by ?ux(?1)6-?(?2)?O??8-?(?3)2(?+?-?) have the same structure as ß- Si3N4. Both elements A1 and A2 reside on Si sites, and both O and N occupy the nitrogen sites of the ß-Si3N4 crystal structure. A molar quantity (z-y) of the A3- anion (defined as a halogen) reside on nitrogen sites.</p> |
