摘要：

In this paper, we prepared SrAl2O4:Eu2+,Dy3+, long persistence phosphorescence enamel coatings by using SrAl2O4:Eu2+,Dy3+ phosphor powders and glass frits and organic vehicle. The glass frits were specially prepared to fit the SrAl2O4:Eu2+,D3+. The prepared phosphorescence enamels were found to have very bright long lasting phosphorescence after being excited by the ordinary fluorescent lamp or sunlight. The emission can be seen even 12h after removal of the exciting source. The emission shows a broad band peaking at 520nm resulted from the transition of 4f-5d of Eu2+ ions in SrAl2O4:Eu2+,Dy3+, The phosphorescence enamels can be used as energy saving display in various applications.
