Fluorescent substance and light-emitting device employing the same |
| abstract |
The embodiment provides a green light-emitting fluorescent substance having high quantum efficiency and also a light-emitting device comprising that substance so as to less undergo color discrepancies. The fluorescent substance is generally represented by (Sr1-xEux)3-yAl3+zSi13-zO2+uN21-w, and is a kind of the Sr3Al3Si13O2N21 phosphors. This substance also gives an X-ray diffraction pattern having a diffraction peak at 2 θ of 15.2 to 15.5 DEG and the half-width thereof is 0.14 DEG or less. Further, the substance emits luminescence having a peak within 490 to 580 nm when excited by light of 250 to 500 nm. The light-emitting device provided by the embodiment comprises that substance in combination with a light-emitting element and a red light-emitting fluorescent substance. |
