Abstract:
A red-emitting phosphor comprises a nitride-based composition represented by the chemical formula M(x/v)M′2Si5-xAlxN8:RE, wherein: M is at least one monovalent, divalent or trivalent metal with valence v; M′ is at least one of Mg, Ca, Sr, Ba, and Zn; and RE is at least one of Eu, Ce, Tb, Pr, and Mn; wherein x satisfies 0.1≦x
