In this paper, the luminescence mechanism of long afterglow material, the commonly used preparation method and the measurement of its luminescence properties are introduced. The research status of Chang Jinhui material in recent years is emphatically analyzed, and the luminescence properties of a series of long afterglow materials are compared. Based on further research on long afterglow material, some suggestions are put forward.
