Tb3+ single doped and Tb3+/Ce3+ co-doped high aluminum blast furnace slag, aluminosilicate luminescent glass was prepared by a high-temperature water-quenching method. The effects of heat treatment and co-doping on the luminous properties of glass were studied. The results show that, after holding at 1 000℃ for 4 h, the glass host crystallizes into Ca2(Mg0.5Al0.5)(Si1.5Al0.5O7), and the luminescence performance drops sharply. The highest luminous intensity of 4%(mole fraction) Tb3+ doped luminous glass is about 12 times higher than of that crystallized. With Ce3+ ions introduced, energy transfer occurs between Ce3+ ions and Tb3+ ions due to multipolar interaction, and the luminous intensity of Tb3+/Ce3+ co-doped luminescent glass reaches nearly 6 times of the Tb3+ single doped. 4%Tb3+/1%Ce3+ co-doped luminescent glass has good luminescence thermal stability at 150℃, and can be used as a green solid-state luminescent material excited by near ultraviolet LED.
