摘要： According to one embodiment, the luminescent material exhibits a luminescence peak in a wavelength ranging from 490 to 580 nm when excited with light having an emission peak in a wavelength ranging from 250 to 500 nm. The luminescent material has a diffraction peak intensity of the largest peak detected at 2θ=30.1-31.1° that is higher than the diffraction peak intensity of the peak detected at 2θ=25.0-26.0° in X-ray diffraction by the Bragg-Brendano method using Cu-Kα line and its composition is represented by (Sr1−xEux)3−yAl3+zSi13−zO2+uN21−w (a part of the Sr may be substituted by at least one selected from Ba, Ca, Mg and Na, 0
