摘　　要：铝酸盐长余辉发光材料是一类新型储能和环保材料，其储光-发光性能受很多因素影响。在介绍以铝酸盐为基质，稀土为激活剂或主激活剂的新型长余辉材料的发光机理模型的基础上，重点综述了粉末粒度、基质结构、原料纯度、助熔剂等多种因素对铝酸盐发光材料长余辉性能的影响，并指出杂质猝灭也是影响其余辉特性的重要因素。Long lasting alkali-earth aluminate phosphor is a new kind of energy-storing ano environment-protecting materials. The luminescent property is affected by many factors. Based on phosphorescence mechanism, the influence of powder size, matrix structure, raw materials and additives on the luminescent properties of phosphors are mainly described in this paper. Finally, It is indicated that impurity quenching is an important factor having influence on afterglow characteristic.
