摘要	Two series of Y3-xCexAl5O12 and Y2.94GdyCe0.06Al5O12 phosphors were synthesized by high-temperature solid reaction method. The influences of doped elements on the luminescence properties were studied by measuring excitation spectra, emission spectra, reflectance spectra, fluorescence lifetimes and the dependence of luminescence intensity on temperatures. The results show that the intensity of the luminescence decreases with the increase of doping concentration. The luminescence decrease is attributed to the partly absorbed excitation photons by YAG host. It means that the host with high doping competes with Ce3+ center for absorbing excitation energy. The competition leads to less Ce3+ excited and weaker luminescence intensity. The luminescence intensity in YAG:Ce phosphors is affected by temperature significantly, and the intensity of the luminescence decreases with the increase of temperature. Moreover, the thermal quenching of YAG:Ce phosphors is affected strongly by the concentration of Gd rather than Ce.
