摘要
本文论述了超长余辉稀土发光材料(SrAl2O4:Eu2+,Dy3+)的合成方法及其发光机理。以聚乙烯醇为基料,添加适当的发光粉及其它助剂研制出一种超长余辉发光涂料,确定出了该涂料的最佳配方,测定了涂料的各种性能,并对影响涂料性能的各种因素进行了探讨。
Synthesis and luminescence mechanism of superlong afterglow rare earth luminescent materials (SrAl2O4:Eu2+,Dy3+) were described. A superlong afterglow luminescent coating was prepared by adding proper dosage of luminescent powder and other aids into polyvinyl alcohol. Optimum formulation for this coating was determined. Various properties of this coating were tested. Factors influencing coating performance were discussed.
