Novel yellow fluorescent body, represented as Ca1-xAlSi4N7:Eux, is provided, composed of Calcium (Ca), Aluminum (Al), Silicon (Si), and Europium (Eu), wherein the x ranges between 0.001 and 0.15 (0.001 < x ≤ 0.15). The yellow fluorescent body is triggered by blue light, thereby yellow light with a color complementary to blue is emitted. A combination of the yellow fluorescent body and a blue luminant device, therefore, can be used to generate white light with warm hue. |
