White emitting light source and luminescent material |
摘要 |
The invention relates to a white emitting light source with an improved luminescent material of the formula (AEN2/3)*b (MN)*c (SiN4/3)*d1 CeO3/2*d2 EuO*x SiO2*y AlO3/2 wherein AE is an alkaline earth metal chosen of the group of Ca, Mg, Sr and Ba or mixtures thereof and M is a trivalent element chosen of the group of Al, B, Ga, Sc with d1>10*d2. In combination with a UV to blue light generating device this material leads to an improved light quality and stability, especially an improved temperature stability for a wide range of applications. |
