摘要：
Ce3+ and Dy3+ ions doped Ca2Al2SiO7 (CAS) phosphors were prepared by the solid-state reaction at 1280 degrees C for 1h. X-ray diffraction patterns confirmed a tetragonal crystalline structure. The luminescent spectra of CAS: Ce3+, Dy3+ phosphors consist a board band with peaking at 420 nm corresponding to the luminescence of Ce3+ ions and narrow lines of Dy3+ ions. The energy transfer from Ce3+ ion to Dy3+ ion is presented and discussed.
