Preparation of long afterglow luminescence ceramic glaze brick with recycling waste glass and its properties

利用传统陶瓷制备方法合成了SrAl2O4:Eu,Dy长余辉发光粉体，该磷光体主发射波长位于520nm，余辉时间长达20h以上．将该发光粉掺人适量的低熔点玻璃料，经780℃烧成30 min合成了性能较好的低温发光釉料．以废玻璃、粘土为主要原料添加其它少量助剂，经过成型、预烧，将低温发光釉料涂覆在其上，在一定温度下烧成，制得长余辉蓄光釉面砖．

SrAl2O4 :Eu, Dy long afterglow luminescence powders were synthesized by the traditional ceramicpreparing method. The main emission peak lies in a 520 nm wavelength, and the afterglow time was longerthan 20 h. The long afterglow luminescence glaze was obtained by calcining the mixture of low melt point B -Si glass and SrAl2O4: Eu, Dy luminescence materials. Waste glass, small amount of additives and clay wereused as the main raw materials of ceramic brick, and the low melting point luminescent glaze was coated onthe ceramic brick. Finally, the long afterglow ceramic glaze brick can be fabricated under suitable synthesisconditions.
