摘要:The light-emitting material of the present invention includes a diplophase compound that is expressed in the following general formula: (Sr, Eu, Dy) (Al, B) · (Sr, Eu, Dy) (Al, B) O wherein x=0.01 to 0.1, the content of the element B is 0.2 to 1.0% by weight, the content of Eu is 0.5 to 3.0% by weigh and the content of Dy is 0.1 to 3.0% by weight. A production method for the light-emitting material of the present invention comprises (1) a step of measuring previously pulverized raw materials, and mixing them to obtain a mixture of raw materials, (2) a step of putting the mixture into a container, heating the mixture at from 850°C to 1200°C for three hours under reducing conditions, maintained the temperature for five to six hours, thereby obtaining a sintered body, (3) a step of stopping the heating operation and cooling the sintered body naturally down to room temperature, and (4) a step of pulverizing the sintered body to obtain the product. In step (2), reduction is carried out using carbon powder.
