WANG Xiaochun LIU Quansheng ZHANG Xiyan JIANG Weiwei TIAN Xueyan HU Jingjie(College of materials and chemical engineering,Changchun university of science and technology Changchun 130022)  
Solvent luminescence scutcheons were prepared by using SrAl_2O_4:Eu~(2+),Dy~(3+) luminescence powder, commercial paints, some reagent as substrates in the paper. This luminescence scutcheon showed high luminous brightness, long persistence, acidproof, alkalineproof and easy to wash. The excitation spectrum indicated that ultra violet and visible light can excite the plate effectively. The emission spectrum is a broad band peaking at 520nm. The plate showed bright yellow-green color in the dark.
