“…Therefore, it has potential applications in the field of white light‐emitting diodes 4–6 . Glass ceramics containing phosphate crystal phase have the advantages of high rare earth ion doping concentration, low dispersion, high optical stability, low phonon energy, large refractive index and good color rendering index, etc., and become excellent matrix material for rare earth ion doping 7,8 …”

Tb 3+ -doped and Eu 3+ /Tb 3+ co-doped transparent glass ceramics containing Na 3 Gd(PO 4 ) 2 crystal phase were prepared by melt crystallization. The types of crystals, grain size, and optical transmittance of the samples were investigated by X-ray diffraction (XRD), scanning electron microscope (SEM), and UV visible absorption spectrometer. The effect of different heat treatment time on grain size, crystal morphology, and light transmittance was also studied. The luminescence performance of transparent glass ceramics was systematically studied by the excitation spectrum, emission spectrum, and the fluorescence lifetime. The optimal doping concentration of Tb 3+ doped and Eu 3+ /Tb 3+ codoped were determined. When the mole percent concentration of Tb 4 O 7 was 0.4%, the strongest green light was obtained at 546 nm ( 5 D 4 ! 7 F 5 ). Meanwhile, the energy transfer process between Eu 3+ and Tb 3+ was discussed.Under the excitation of 374 nm, white light can be obtained by adjusting the concentration ratio of Eu 3+ and Tb 3+ .
