Development of New Red Phosphor Na(3)YSi(2)O(7):Eu(3+) for a white LED

New red phosphors Na(3)YSi(2)O(7) was prepared by a conventional solid-state reaction. This silicate phosphor can be efficiently excited by near UV light, yielding an intense red emission. Under the excitation of near UV light, the emission intensity is higher than that of a commercial red phosphor...

Description
Summary:New red phosphors Na(3)YSi(2)O(7) was prepared by a conventional solid-state reaction. This silicate phosphor can be efficiently excited by near UV light, yielding an intense red emission. Under the excitation of near UV light, the emission intensity is higher than that of a commercial red phosphor Y(2)O(2)S:Eu(3+).
