1. A phosphor for absorbing light in a region from ultraviolet to visible light and emitting light whose emission peak wavelength being in a range of 600 nm to 650 nm,
wherein a general formula is:
SrtCavEuwAlxSiyNz (wherein 0.5≦t<1, 0<v≦0.5, 0.01<w≦0.03, t+v+w<1, 0.90≦x≦1.1, 0.90≦y≦1.1, 2.5≦z≦3.5); and wherein a difference between the emission peak wavelength and a half width is larger than 543 nm. |
