Alkaline earth silicates. which comprise a host material doped with rare-earth minerals, show excellent luminescence properties with various crystal structures and high stability. From results of this study, we report luminescence properties of Ba(9)Sc(2)Si(6)O(24):Eu(2+) and Ba(9)Sc(2+delta)Si(6)O(24+3 delta)N(3 delta):Eu(2+) as a novel alkaline earth silicate and silicon oxynitride phosphors for white LEDs Using a conventional solid-state reaction, Ba(9)Sc(2)Si(6)O(24):Eu(2+) samples were synthesized and Ba(9)Sc(2+delta)Si(6)O(24+3 delta)N(3 delta):Eu(2+) samples were obtained by nutrization of Ba(9)Sc(2+delta)Si(6)O(24):Eu(2+) The samples can be excited by blue light, exhibiting green (Ba(9)Sc(2)Si(6)O(24):Eu(2+)) and yellow (Ba(9)Sc(2+delta)Si(6)O(24+3 delta)N(3 delta):Eu(2+)) efficiently, which are emissions for use in white LEDs essentially.
