A JEM phase phosphor having superior luminous efficiency is obtained, and a light emitting device is provided, which includes first and second phosphors and in which fluorescence from the first phosphor is not much absorbed by the second phosphor, with the JEM phase phosphor used as a first phosphor. The first phosphor is the JEM phase phosphor having optical absorption of at most 30% at a wavelength in a relation of complementary color to the emission wavelength of the first phosphor. In the light emitting device having a combination of the first phosphor and the second phosphor emitting fluorescence of longer wavelength than the first phosphor, the first phosphor has optical absorption at the emission wavelength of the second phosphor of at most 30%. |
