In this paper structural, thermal and optical properties of Er³⁺ doped germanate glasses with the composition of 63.0GeO₂-9.8Ga₂O₃-11.1BaO-4.9X-8.8Na₂O-2.5Er₂O₃ (in mol%), where X = ZnO, TiO₂, Al₂O₃ and Y₂O₃ are reported. The investigated glasses exhibit low phonon energies (<1000 cm⁻¹) and high glass transition temperature varying between 588 and 642 °C. The Raman spectra evidence about different polymerization degree of the glasses. The thermal treatment leads to the precipitation of various crystals, the composition of which depends on the glass composition. According to the spectroscopic properties Er³⁺ ions are suspected to have similar local environment in the as-prepared glasses. However, Er-doped crystals are expected to precipitate upon devitrification, which leads to significant change of the spectroscopic properties, in particular increase in the intensity of upconversion and MIR emissions is observed. It is demonstrated that the glasses with Y₂O₃, ZnO and TiO₂ are promising glasses especially for MIR applications.
