The GeO2 modified high-concentration Er3+/Yb3+ co-doped phosphate glasses with composition 64P2O5–2ZnO–13BaCO3–13K2CO3–8Al2O3–0.5Er2O3–12Yb2O3–xGeO2 mol% (PEYG, x = 0, 2.5, 5, 7.5, and 10) were successfully prepared by the melt-quenching method. The structure and spectroscopic properties were revealed by analyzing refractive index, expansion coefficient, glass transition temperature, absorption and emission spectra, and laser properties. We studied the relationship between GeO2 doping content and spectroscopic properties, finding that GeO2 could enhance 1535 nm emission of the PEYG glasses. The PEYG modified with 5 mol% GeO2 showed the best spectroscopic properties. The study provided a good guidance for the design of high gain laser glasses and fibers.

The Er3+/Yb3+ co-doped phosphate glasses with GeO2 modification (PGs) were successfully prepared by melt-quenching method. Their physical parameters were investigated such as density, refractive index, glass transition temperature and coefficients of thermal expansion. The phenomenological intensity parameters Ω t (t = 2, 4, 6) of the PGs have been calculated by the Judd-Ofelt theory. The relationship between optical properties and GeO2 concentration was discussed in this work. The laser experiment using PG10 (GeO2 10 mol% modified phosphate glass with Er3+/Yb3+ ratio of 0.5/2) was carried out. The research results indicate that the introduction of GeO2 results in a large absorption and emission cross-section, a long lifetime, a high quantum efficiency, and an excellent laser performance. All these advantages could also portend an optimized method for improving spectroscopic properties in other constituent Er3+/Yb3+ co-doped phosphate glass by introducing GeO2.
