N2 - Ce/Tb/Eu co-doped lithium–barium borophosphate glasses were successfully synthesized by melt quenching method. The structure and luminescence properties of glasses were characterized by Fourier transform infrared spectroscopy, photoluminescence spectra spectroscopy and colorimetric analysis. The influence of matrix composition on glass structure and photoluminescent properties was investigated in detail. The partial replacement of BaO for B2O3 changed the ratios of Ce3+/Ce4+ and Eu2+/Eu3+, and altered the glass structure, which affected the physical properties of the glass samples. The emission intensity of Ce3+, Eu2+ and Tb3+ decreased with increasing BaO content, but the intensity of Eu3+ increased continuously. Energy was transferred from Ce3+, Tb3+and Eu2+ to Eu3+ ions, which resulted in the enhancement of Eu3+ luminescence intensity. Meanwhile, the colors of Ce/Tb/Eu co-doped luminescent glasses changed from cold white to warm white by changing glass matrix composition. Possible mechanisms of the reduction for valence-variable rare earth ions were also discussed.
