In this work, Er³⁺/Yb³⁺ co-doped 40Bi₂O₃-30GeO₂-15Ga₂O₃-15Na₂O glass was papered by melt-quenching method. The thermal properties and spectroscopic were studied. The glass has good thermal stability and the maximum phonon energy is 750 cm⁻¹, which is benefited for 1.53 μm emission. According to the J-O theory and absorption spectra, the J-O intensity parameters were calculated, the spectral quality factor χ = Ω₄/Ω₆ of BGGN4 glass is 2.236. Under 980 nm excitation, the 1.53 μm luminescence characteristics of these glasses were studied. When the Er³⁺/Yb³⁺ ions doping concentration ratio (mol%) reaches 0.5:1.0, the maximum fluorescence intensity can be obtained, and the maximum emission cross section is 6.4 × 10⁻²¹cm². The maximum stimulated gain coefficient in the 1.53 μm band is 4.6 cm⁻¹. Finally, the up-conversion emission and energy transition mechanism of Er³⁺/Yb³⁺ co-doped BGGN glass were studied. The results indicate the prepared Er³⁺/Yb³⁺ co-doped bismuth germanate glass have good gain performance and is an ideal 1.53 μm laser gain material.
