摘要：

This study investigates the luminescence and physical properties of tellurite-based glass co-doped with europium (Eu3+) and terbium (Tb3+) ions. The glass composition, 30TeO2: 20B2O3: (20 - x)SiO2: 10Na2O: 15BaO: 5Tb2O3: xEu2O3, was synthesized via a melting process at 1100 degrees C followed by annealing at 500 degrees C for 3 h. The optical characterization included absorption spectra, photoluminescence under 378 nm excitation, where a quenching effect was observed at 5.0 mol% Eu2O3, significantly influencing the emission intensity and suggesting an optimal doping concentration for enhanced performance, and Commission Internationale de l'E<acute accent>clairage (CIE) 1931 colorimetric analysis. Lifetime measurements were conducted to explore decay kinetics, while an energy transfer efficiency model highlighted the interaction dynamics between Tb3+ and Eu3+ ions. The Energy transfer efficiency showcases promising results for applications in photonics. This work provides insights into the synergistic effects of rare-earth co-doping on the luminescence behavior of tellurite-based glasses.
