Phosphor, method of producing the same, and light emitting apparatus

A light emitting apparatus comprising a light emitting device that emits primary light, and a light converter that absorbs part of said primary light and emits secondary light having a longer wavelength than that of said primary light, wherein said light converter includes at least any one selected from a green-based luminous phosphor, an yellow-based luminous phosphor and a red-based luminous phosphor,

• said green-based luminous phosphor being β-type SiAlON substantially represented by
• General formula (A):
• EuaSibAlcOdNe
• (in the General formula (A), 0.005≦a≦0.4, b+c=12, and d+e=16 are satisfied), said green-based luminous phosphor being a divalent europium-activated oxynitride phosphor having reflectance of light emission in a longer wavelength region of visible light than a peak wavelength of 95% or larger,
• said yellow-based luminous phosphor being α-type SiAlON substantially represented by
• General formula (B):
• MIfEugSihAlkOmNn
• (in the General formula (B), MI represents at least one kind of element selected from Li, Na, K, Cs, Mg, Ca, Sr and Ba, and 0<f≦3.0, 0.005≦g≦0.4, h+k=12, and m+n=16 are satisfied), said yellow-based luminous phosphor being a divalent europium-activated oxynitride phosphor having reflectance of light emission in a longer wavelength region of visible light than a peak wavelength of 95% or larger, said red-based luminous phosphor being a divalent europium-activated nitride phosphor substantially represented by
• General formula (C):
• (MIIl-pEup)MIIISiN3
