| titleOfInvention | Phosphor, light emitting device and light source |
| abstract | A phosphor having an excitation band relative to lights in the wide range of wavelengths from ultraviolet to visible light, and having an emission spectrum in the red range and so on, with a wide half value width, and an LED and a light source using the phosphor and emitting white and other color lights with good color rendering properties are provided. Powdered raw materials of Ca 3 N 2 (2N), CaO (2N), AlN (3N), Si 3 N 4 (3N), and Eu 2 O 3 (3N) are prepared, and the respective raw materials are mixed to have a mole ratio of the respective elements of Ca: Al: Si: Eu = 0.985: 1: 1: 0.015. The mixed raw materials are fired at 1000°C or higher in an inert atmosphere for three hours, and thereafter pulverized to obtain a phosphor having a composition of CaAlSiN 2.83 O 0.25 : Eu, which is one example of the phosphor satisfying the above described object. Furthermore, by combining the phosphor with an appropriate LED or a light source emitting from ultraviolet light to visible light, the LED and the light source emitting white and other color lights with good color rendering properties can be obtained. |
