Synthesis of Long Afterglow Phosphor CaAl2Si2O8 : Eu2 +, Dy3 + via Sol-Gel Technique and Its Optical Properties

The long afterglow phosphor CaAl2Si2O8 : Eu2 +, Dy3 + was prepared by a sol-gel method. The sol-gel process and the structure of the phosphor were investigated by means of X-ray diffraction analysis (XRD) . It is found that the single anorthite phase formed at about 1000 DGC, which is 300 deg C lowe...
