Raman-Scattering Properties of Er-Doped Alkaline Tellurite Glasses for Lasing Applications

Abstract

Alkaline tellurite glasses within composition of 65TeO2–9Nb2O5–5Li2O–15LiCl–5PbO–1.0La2O3 xEr2O3 ions doped (where x is 0, 20000, 25000 and 30000 ppm) have been prepared by the quenching melting method. Herein, parameters such as Judd–Ofelt, Ωt (t = 2, 4, 6) has been estimated. Transfer probabilities quality factors, magnetic and electric radiative oscillator strength fluorescence are used for a number of different excited states. Moreover, the structure of prepared glasses was investigated using Raman spectra. Physical and spectroscopic characterizations of Er3+ doped these glasses, which imply that we can fabricate them as potential candidates for optical application.
