co-doped YAG ceramics were mainly studied by X-ray diffraction (XRD) and photoluminescence spectroscopy
respectively. XRD results show that the single YAG crystal phase is obtained when the precursor is sintered at 1 750 ℃. The linear transmission of the ceramic in visible range reaches about 70%. Under the excitation of 430 nm
the ceramic shows the characteristic emission peaks of Ce
