摘　　要：As a leader of long persistent luminescence(LPL) materials, the optical properties of aluminate phosphor have remained unsurpassed for many years. As a powder material, its practical application will always be limited to the field of security signs. In this paper, the SrAl_(2)O_(4)∶Eu^(2+), Dy^(3+)inorganic solid material with comparable LPL properties to powder materials was obtained. The crystallization mechanism and crystallite micro-morphology of inorganic glass materials have been studied, and a new opinion is put forward that the large-size SrAl_(2)O_(4)crystallites in the glass matrix are stacked by rod-shaped crystals arranged in a regular direction. In addition,the SrAl_(2)O_(4)∶Eu^(2+), Dy^(3+)glass obtained cannot only collect high-energy photons but also is sensitive to lowenergy sunlight. The results show that the material exhibits superior performance in LPL, thermoluminescence,and photostimulable luminescence. Based on this property, a new application of this material in the field of information storage was explored. This paper has a certain reference value for the development and application of aluminate LPL materials in the field of smart optical information storage.
