Sr4Al14O25: Eu2+, Dy3+ luminescent ceramics with high brightness and long afterglow were prepared using glass frits as binders by sintering at lower temperature and air atmosphere. The effects of glass frits on the properties of luminescent ceramics were discussed. The analytical results indicate that the surface structure and adhesion with phosphor are influenced by glass frits and sintering temperature. When sintered at 850°C, the samples with frit1 or frit2 obtained good surface morphology and good adhesion. The sample with frit2 sintered at 850°C yielded the better surface morphology and good adhesion. The sample with frit1 sintering at 850°C possessed the better luminescent properties.
