“…Among trivalent RE ions, the luminescence features of the Pr 3+ ion have became more popular because of its specific 4f 2 configuration, possessing 91 degenerate energy levels [9,10]. The tellurite glass systems doped with Pr 3+ ions have been widely studied for their structural details and luminescent properties [3,[11][12][13][14][15]. Moreover, due to the low phonon energies mentioned above, the fluorescence intensity of Pr 3+ -doped tellurite glasses has been observed to be several times larger than that of other glass systems [16][17][18].…”

Abstract:The goal of this work was to investigate the spectroscopic properties of Pr 3+ ions, embedded in two different tellurite glass matrices, TeO 2 -WO 3 -PbO-La 2 O 3 and TeO 2 -WO 3 -PbO-Lu 2 O 3 . The absorption and fluorescence spectra have been recorded and analyzed in terms of the Judd-Ofelt theory along with the luminescence decay of the 3 P 0 and 1 D 2 levels of the Pr 3+ ion. The spectroscopic studies were completed with ellipsometric measurements providing the dispersion relation of the refractive index of the investigated glasses.
