“…Prior works indicated that various rare earth (Tb 3+ , Sm 3+ , Pr 3+ , and Ce 3+ )-and transition metals (Mn 2+ , Cu 2+ , and Co 2+ )-activated zinc borosilicate glasses have been studied to investigate luminescence properties [15][16][17][18][19][20][21][22]. Furthermore, the effect of adding transition metals (Nb, Mn, V, and Co) on the crystallization behavior of zinc borosilicate glasses has been examined [18,[22][23][24]. However, in those studies, the effect of substituting zinc oxide with silicon dioxide and boron oxide on the luminescence behavior of zinc borosilicate glasses was not investigated in detail.…”

In this study, terbium-doped ZnO-SiO2-B2O3-Na2O glasses were fabricated with the conventional melt-quenching method. The effect of altering the concentration of the host matrix on luminescence performance was investigated in terms of different ZnO/B2O3 and ZnO/SiO2 ratios. FT-IR results indicate that bridging oxygens (Bos) were converted to non-bridging oxygens (NBOs) with increments of ZnO. Furthermore, the emission intensity and luminescence lifetime of samples were influenced by the amount of ZnO; this was proven with photoluminescence spectra results. The maximum emission intensity was observed at a 1.1 ZnO/B2O3 ratio and a 0.8 ZnO/SiO2 ratio; however, the highest luminescence lifetime was observed at a 1.1 ZnO/SiO2 ratio. The emission intensity and luminescence lifetime of glass samples were improved by heat treatment as a result of the formation of willemite and zinc oxide phases. An increase in the ZnO/SiO2 ratio facilitated the formation of willemite and zinc oxide phases; therefore, crystallinity was directly related to the luminescence behavior of glass samples.
