Abstract

Glasses based on TeO₂-BaO-MgO-ZnO-Na₂O have been made successfully. The Raman scattering and the transmission properties were measured, and the photoluminescence properties of Pr³⁺ doped tellurite glasses were studied. Tellurite glasses exhibit an IR transmission cut- off beyond approximately 6 micrometers . The maximum-phonon band is at 745 cm^-1. The emission from the Pr³⁺:¹G₄ yields ³H₅ transition is at 1.295 micrometers wavelength with a spectral bandwidth of 30 nm. Pr³⁺ doped tellurite glasses appear to be a promising candidate for waveguide amplifiers in the 1.3 micrometers telecommunication window.
