| 摘 要： | 采用电弧法制备出ＳｒＡｌ２Ｏ４：Ｅｕ＾２＋长余辉发光陶瓷，通过荧光光谱和激发光谱研究了它的发光和余辉特性，结果表明，陶瓷的发光衰减与多晶粉末磷光体相同，也是由初始的快衰减与后期的慢衰减的构成，但余辉的特征明显好于多晶磷光体，而且耐环境性能得到显著地改善。

| Abstract: | Luminescent chinaware of long persistence of S rA l 2O 4:Eu- 2+ has been prepared with using arc method.Fluorescence an d excitation spectra were measured in order to study its luminescence and long p ersistence properties.Results show that both of luminescent chinaware and polycr ystalline powdered phosphor are the same in luminescence decay and consist of an initial fast process and a later extremely slow process.Long persistence proper ties of luminescent chinaware are better more than polycrystalline powdered phos phor,and its function of environment-resistant has been improved prominently. |
