In recent years, rare earth doped optical materials have been widely used in w-LEDs, optical displays and lasers. Glass ceramics containing titanate crystal phases are widely used in the matrix of luminescent materials because of their high thermal and chemical stability, excellent luminescence properties, and low phonon energy. However, Y2Ti2O7 with a pyrochlore structure is considered a good up-conversion luminescent matrix owing to its low phonon energy (⪅712 cm-1). By the melt crystallization, Tb3+ doped transparent glass ceramics (GCs) were prepared. Y2Ti2O7 crystal phase in glass ceramics was decided by using x-ray diffraction. The light transmittance of the glass ceramics can reach 71% in the visible region. The emission intensity is the strongest when the doping concentration of Tb3+ is 0.4%. Compared with the precursor glass, glass ceramics have higher luminescence intensity. It can be concluded that Tb3+ doped transparent glass ceramics containing Y2Ti2O7 crystal can be used in green light emission fields.
