Pr3+/Nd3+ codoped tellurite glass for O+E+S-band broad emission

In this work, Pr3+ was introduced into Nd3+-doped tellurite glass with composition TeO2-ZnO-Na2O-Nb2O5 to achieve broadband near-infrared emission. A broadband fluorescence emission ranging from 1 250 nm to 1 530 nm was obtained under the excitation of 808 nm LD, which is contributed by the Pr3+:1D2 →1G4 and Nd3+:4F3/2→4I13/2 transitions emitting the fluorescence located at around 1.47 µm and 1.35 µm bands, respectively. The 1.47 µm band fluorescence of Pr3+ is attributed to the energy transfer from Nd3+ to Pr3+ ions and the energy transfer mechanism was further investigated by calculating relevant micro-parameter and phonon contribution ratio. Meanwhile, the studied tellurite glass possesses good thermal stability. The present work indicates that Pr3+/Nd3+ codoped tellurite glass is an excellent gain medium for potential O+E+S-band broad optical amplifiers.
