This work deals with a systematic study of optical, structural and thermal properties of the
TeO2-BaO-ZnO (TBZ) glasses and their ability for doping with Er3+ ions in order to achieve
the ≈1.5 µm Stokes photoluminescence and upconversion photoluminescence emission
in visible and near-infrared spectral region. The structure of synthesized TBZ glasses was
investigated by Raman scattering.
