摘要:
This specification discloses methods of enhancing the stability and performance of Eu2+ doped narrow band red emitting phosphors. In one embodiment 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+y−zSizO4−4y−zN4y+z:Eux (AE=Ca, Sr, Ba, or a combination thereof, 0
