Narrow band emitting SiAlON phosphor

This specification discloses a method of enhancing the stability and performance of Eu2+ doped narrow band red emitting phosphors. The resulting phosphor compositions are characterized by crystallizing in ordered structure variants of the UCr4C4 crystal structure type and having a composition of AE1...

Beschreibung
Zusammenfassung:	This specification discloses a method of enhancing the stability and performance of Eu2+ doped narrow band red emitting phosphors. The resulting phosphor compositions are characterized by crystallizing in ordered structure variants of the UCr4C4 crystal structure type and having a composition of AE1−xLi3−2yAl1+2y−zSizO4−4y−zN4y+z:EUx(AE=Ca, Sr, Ba; 0
