A high luminance light emitting phosphor having CaAlSiN 3- based crystals as a parent crystal, a method for producing the same, and a use thereof are provided. In the present invention, the phosphor contains at least elements of lithium (Li), calcium (Ca), silicon (Si), aluminum (Al), oxygen (O), nitrogen (N), and cerium (Ce), and CaAlSiN 3 crystal or a crystal having the same crystal structure as CaAlSiN 3 is used as the parent crystal. By controlling the composition of the phosphor, it is possible to produce a phosphor that emits yellow, orange, or red light emission colors. |
