<p>Phosphors comprising a nitride-based composition represented by the chemical formula: M(x/v)(M'aM"b)Si(c-x)A1xNd :RE, wherein: M is a divalent or trivalent metal with valence v; M' is at least one divalent metal; M" is at least one trivalent metal; 2a + 3b + 4c = 3d; and RE is at least one element selected from the group consisting of Eu, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb. Furthermore, the nitride-based composition may have the general crystalline structure of M'aM"bSicNd, where A1 substitutes for Si within the crystalline structure and M is located within the crystalline structure substantially at the interstitial sites.</p> |
