摘要： Tm$^{3+}$/Tb$^{3+}$ co-doped TeO$_{2}$-GeO$_{2}$-Bi$_{2}$O$_{3}$-BaF$_{2}$ glasses were synthesized via high-temperature melt-quenching to achieve blue-green fluorescence emission. Under 808-nm pump excitation, the TGBB2 sample (Tm$_{2}$O$_{3}$:Tb$_{4}$O$_{7} = 3:8$) exhibited balanced emissions at 452 nm (blue, Tm$^{3+}$: $^{1}$G$_{4}\to\,{}^{3}$H$_{6}$) and 544 nm (green, Tb$^{3+}$: $^{5}$D$_{4}\to\,{}^{7}$F$_{5}$). With increasing Tb$^{3+}$ concentration, green emission intensity increased while blue emission decreased, confirming efficient Tm$^{3+}\to $Tb$^{3+}$ energy transfer. Key performance metrics for TGBB2 included: a forward energy transfer coefficient of 571.83$\times10^{-40}$ cm$^{6}$/s (far exceeding the reverse coefficient of 63.12$\times10^{-40}$ cm$^{6}$/s), an energy transfer efficiency of 99.5%, maximum emission cross-sections of 5.87$\times10^{-21}$ cm$^{2}$ (476 nm, Tm$^{3+}$) and $3.37\times 10^{-21}$ cm$^{2}$ (486 nm, Tb$^{3+}$), and corresponding gain coefficients of 2.98 cm$^{-1}$ and 0.46 cm$^{-1}$. These results validate the glass's low laser threshold, making Tm$^{3+}$/Tb$^{3+}$ co-doped tellurite-germanate-bismuthate glass a promising candidate for blue-green laser communication and underwater optical transmission.
