    摘要： The present invention provides a red fluorescent substance and a light-emitting device utilizing the substance. This device less suffers from color drift even when working with high power. The light-emitting device comprises a blue LED, a green fluorescent substance of Sr3Al3Si13O2N21 activated with a luminescent center, and the red fluorescent substance. The red fluorescent substance contains an inorganic compound comprising a metal element M, a trivalent element M1 other than the M, a tetravalent element M2 other than the M, and nitrogen element. In the inorganic compound, the M is partly replaced with a luminescent center element EC. The red fluorescent substance has basically the same crystal structure as Sr2Al3Si7ON13. The red fluorescent substance emits luminescence having a peak in the range of 580 to 650 nm when excited with light of 250 to 500 nm.
