Green-emitting Y3Al5O12: Tb phosphor materials have been widely studied because of theirhigh luminescence efficiency and stability under the conditions of high irradiance with an electron beam.In this paper, Green-emitting phosphor of yttrium aluminum garnet (Y3Al5O12 or YAG) doped with Tb3+,Ce3+ and Gd3+ was synthesized by sol-gel method. By means of TG/DSC, XRD, and photoluminescence(PL) performance, the sintering condition and its influence on the powder’s emitting performance werestudied. The experimental results showed that, Y2.8Tb0.12 Ce0.08-x GdxAl5O12 synthesized by sol-gelmethod was a kind of phosphor of good performance. When the value of x was set at 0.04, the bestemitting performance was obtained. The Y3Al5O12: Tb, Ce, Gd particles had fine size, spherical shape,filled morphology, high crystallinity, and good brightness
