Title: Spectroscopic properties of Er{sup 3+} doped lead telluroborate glasses for 1.5 μm broadband amplifiers

Er{sup 3+} doped lead telluroborate glasses (xEPTB) with the composition 25B{sub 2}O{sub 3}-(25-x)TeO{sub 2}-25PbO-10Bi{sub 2}O{sub 3}-15CdO-xEr{sub 2}O{sub 3} (where x=0.1, 0.5, 1 and 2 wt%) have been prepared and characterised using NIR luminescence and decay measurements for 1.5 μm broadband amplifier applications. Judd-Ofelt intensity parameters have been derived to predict radiative properties of the {sup 4}I{sub 13/2}→{sup 4}I{sub 15/2} emission transition. The larger values of stimulated emission cross-section (σP), FWHM, gain bandwidth (ΔG), radiative lifetime (τ{sup cal}), quantum efficiency (η) of the 1EPTB glass suggest their potential use in broadband amplifiers. The effect of RE ion concentration and OH{sup −} content on the lifetime of {sup 4}I{sub 13/2}→{sup 4}I{sub 15/2} transition and the energy transfer mechanism of Er{sup 3+} ions have also been discussed and reported in the present study.
