Abstract: This study employed a high-temperature melting method to prepare Tb3+/Eu3+ co-doped B 2 O 3 -ZnO-Sb 2 O 3 -SrO (ZBSS) glass systems. By modulating the Eu3+ concentration (0.3–1.5 mol%), the structural, optical properties, and energy transfer mechanisms were systematically investigated. XRD and FTIR confirmed all samples were single amorphous. Eu3+ enhanced glass network compactness, increasing density (3.2557–3.3128 g/cm3) and oxygen packing density (85.487–85.916 mol/L), both increasing with Eu3+ content. Under 377 nm excitation, the maximum ET efficiency from Tb3+ (5D 4 →7F 5 , 544 nm) to Eu3+ (5D 0 →7F 2 , 614 nm) was 26.96%, dominated by dipole-dipole interactions. Efficient ET realized continuous green-to-yellow emission tuning, with CIE coordinates (0.4023∼0.4632, 0.4488∼0.4802) and CCT 3139–3938 K (yellow range). The glass had quantum efficiency 30.48%–33.71% and excellent thermal stability (0.2122 eV activation energy), retaining 51.78% of room-temperature emission at 473 K. In conclusion, Tb3+/Eu3+ co-doped ZBSS glasses achieve tunable yellow emission via efficient ET, with high transparency and stability, promising for solid-state lighting and LEDs.
