The invention provides a production method of aluminate matrix phosphor, comprising seven steps as follows: pretreatment of raw materials, mixing of wet method, primary high-temperature air synthesis, primary smashing and grading, secondary high-temperature reduction, secondary grading and surface coating; finally the aluminate phosphor product with the surface coated with MgO film can be prepared. The method of the invention completely combines the advantages of wet chemical method, solid-phase reaction method, and modern air smashing and grading technology; the use of pretreatment of the raw materials for synthesis and the mixing process of wet method improves the reaction activity of the raw materials for synthesis; at the same time, the combination of the high-temperature solid-phase method and the air grading technology can achieve the effective control over the central grain size and distribution of the phosphor; finally the phosphor product of high luminous efficiency, fine grain size and centralized distribution can be prepared; the invention has significant application prospects.
