【Abstract】 SrAl 2O 4:Eu,Dy long afterglow luminescence powders were synthesized by the traditional ceramic preparing method. The main emission peak lies in a 520 nm wavelength, and the afterglow time was longer than 20 h. The long afterglow luminescence glaze was obtained by calcining the mixture of low melt point B-Si glass and SrAl 2O 4:Eu,Dy luminescence materials. Waste glass, small amount of additives and clay were used as the main raw materials of ceramic brick, and the low melting point luminescent glaze was coated on the ceramic brick. Finally, the long afterglow ceramic glaze brick can be fabricated under suitable synthesis conditions.更多还原
