摘要
A method of providing a phosphor with a precisely controlled element composition, a phosphor provided by the same, and a red phosphor represented by the [formula 1] are disclosed, in which; CaaSrbAlcSidOeNf:Eug [formula 1]wherein 0≦a1, 0≦b1, c=1, 0.8≦d≦1.2, 0≦e≦0.5, 2.5≦f≦3.1, 0.002≦g≦0.020, a and b are not both 0 at the same time; anda CIE1931 chromaticity coordinates (x, y) of a light emitted from the phosphor, which is excited by a wavelength of 455 nm, satisfies the formulae:; x=[(−0.1059b3+0.068b2−0.06b)+(2152.8g3−309.2g2+8.2943g)+0.6324]±0.01;; y=[(−0.1295b3−0.0968b20.0702b)+(−3299.2g3311.08g2−7.9266g)+0.3621]±0.01.;The present invention also provides a light emitting device comprising the said red phosphor.
